When hearing the phrase DigitalOcean to AWS migration, the first thing that often comes to mind is moving virtual machines and servers between the two cloud platforms. However, depending on the current environment that’s set up on DigitalOcean, it might extend to more than just this.
DigitalOcean offers a variety of cloud services including Droplets, Volumes, Spaces, Managed Databases, Kubernetes, Load Balancers, and networking services. AWS provides equivalents for most of these capabilities, but the architecture, interconnectivity, security controls, and operational model are significantly different.
So depending on which services you use on DigitalOcean and which migration strategy you decide for each workload, the details of the migration will differ.
A successful migration therefore requires two decisions:
- What should be moved as-is?
- What should be redesigned using an AWS-native service?
For example, a DigitalOcean Droplet can be migrated to Amazon EC2 as a lift-and-shift operation. But a different migration strategy (i.e. refactoring) that involves redesigning the app into a microservices architecture, might move the application totally or partially to ECS, EKS, and lambda.
This guide explains how to migrate the major DigitalOcean services to AWS, including practical examples, migration strategies, commands, architecture considerations, downtime reduction techniques, and post-migration validation.
1. DigitalOcean-to-AWS Service Mapping
The first step in preparing for the migration is to create an inventory of everything running in DigitalOcean. Then you can list the potential equivalent AWS services that can be used and correspond to each DigitalOcean service.
A typical mapping looks like this:
| DigitalOcean | AWS equivalent | Typical migration approach |
| Droplets | Amazon EC2 | Rebuild or rehost |
| Droplet snapshots | EC2 AMIs / EBS snapshots | Recreate or convert |
| Volumes | Amazon EBS | Copy data |
| Spaces | Amazon S3 | Object-storage migration |
| Managed PostgreSQL | Amazon RDS PostgreSQL / Aurora PostgreSQL | DMS, dump/restore |
| Managed MySQL | Amazon RDS MySQL / Aurora MySQL | DMS, dump/restore |
| Managed Redis | ElastiCache for Redis/Valkey | Replication or application-level migration |
| Kubernetes | Amazon EKS | Recreate cluster and migrate workloads |
| Container Registry | Amazon ECR | Push/copy container images |
| Load Balancer | Elastic Load Balancing | Recreate configuration |
| VPC | Amazon VPC | Redesign/recreate |
| Cloud Firewall | Security Groups / Network ACLs | Recreate rules |
| Reserved/Floating IP | Elastic IP | Reconfigure DNS/application |
| DNS | Route 53 | Transfer/recreate zones |
| Monitoring | CloudWatch | Recreate dashboards/alarms |
| CDN | CloudFront | Reconfigure distribution |
| Functions | AWS Lambda | Rebuild/adapt functions |
| App Platform | ECS, EKS, Lambda, or EC2 | Depends on application |
| Managed Kubernetes databases | RDS/Aurora/DynamoDB/ElastiCache | Usually redesign |
The important point is that there isn’t always a one-to-one mapping.
DigitalOcean’s relatively simpler model might not always have a direct AWS alternative service with exactly the same behavior. In that case, treat the migration as an opportunity to set up an AWS architecture that best matches each workload.
2. Start With a Complete DigitalOcean Inventory
The next step is to document every workload’s related specs and infrastructure resources.
For every application, record:
- Droplet name
- Droplet size
- Operating system
- Region
- Public IP
- Private IP
- Attached Volumes
- CPU utilization
- RAM utilization
- Disk utilization
- Network traffic
- Open ports
- Firewall rules
- Running services
- Cron jobs
- Systemd services
- Environment variables
- Secrets
- SSL certificates
- DNS records
- Database connections
- Object-storage dependencies
- Container images
- Backups
- Monitoring
- External integrations
For example:
Application: ecommerce.example.com
DigitalOcean:
Droplet: web-01
Size: 4 vCPU / 8 GB RAM
OS: Ubuntu 24.04
Region: NYC
Volume: 200 GB
Database:
Managed PostgreSQL
4 vCPU / 8 GB RAM
150 GB storage
Storage:
Spaces bucket: ecommerce-assets
Networking:
Cloud Firewall
Ports: 80, 443, 22
DNS:
ecommerce.example.com
www.example.com
Background jobs:
cron
Redis
Containers:
Docker Compose
This inventory becomes the migration blueprint which you’ll evaluate and plan the migration destination accordingly.
3. Decide on the Migration Strategy
As we mentioned, a migration strategy can influence the decision of the destination AWS service to be used. Therefore, using the directly mapped AWS service corresponding to the DigitalOcean service might not always be the choice.
There are three common approaches.
Strategy 1: Rehost
Move the workload with minimal architectural changes.
For example:
DigitalOcean Droplet → Amazon EC2
This is usually the fastest approach.
It is appropriate when:
- You need a quick migration.
- The application is stable.
- You don’t want major application changes.
- You want to migrate first and modernize later.
Strategy 2: Replatform
Move the application but replace some infrastructure with managed AWS services.
For example:
DigitalOcean:
Droplet
│
├── Application
├── PostgreSQL
└── uploaded files
↓
AWS:
EC2
│
├── Application
│
└── Amazon RDS PostgreSQL
Amazon S3
└── uploaded files
This is often the best compromise.
You retain much of the existing application while reducing infrastructure-management responsibilities.
Strategy 3: Refactor
Redesign the application around AWS-native services.
For example:
┌── CloudFront
│
Users ── Route 53 ── ALB ── ECS
│
├── RDS/Aurora
│
├── ElastiCache
│
└── S3
This can provide better scalability and availability but requires considerably more engineering effort.
4. Migrating DigitalOcean Droplets to AWS EC2
A DigitalOcean Droplet is essentially a virtual machine, and Amazon EC2 is the equivalent AWS service that’s typically the destination of migrating a virtual machine in a life-and-shift strategy.

There are two main approaches for implementing this:
Approach A — Rebuild the server
This is simply achieved by creating a new EC2 instance and installing the application components.
For example, suppose the DigitalOcean server runs:
Ubuntu
Nginx
PHP 8.3
Laravel
Instead of copying the entire machine, you could create:
EC2 Ubuntu / CentOS / Windows
↓
Install Nginx
↓
Install PHP
↓
Deploy Laravel
↓
Restore configuration
This produces a cleaner AWS architecture.
This is usually preferable when the application can be reproduced through:
- Ansible
- Terraform
- Cloud-init
- Docker
- Packer
- Configuration-management scripts
Approach B — Rehost the VM
If preserving the existing server is important, you can migrate the machine image.
AWS VM Import/Export supports importing VM images into EC2. The AWS workflow involves exporting the VM image, uploading it to Amazon S3, and importing it into EC2.
AWS Application Migration Service is another option for supported workloads and is specifically intended for lift-and-shift server migrations. AWS identifies it as the primary migration service for lift-and-shift migrations in its Migration Hub documentation.
Choosing the Correct EC2 Instance
Don’t automatically select an EC2 instance based on the DigitalOcean droplet CPUs and memory specs, but rather try to measure the actual utilization of the droplet to decide the application needs.
A 4-vCPU DigitalOcean Droplet isn’t necessarily equivalent to a particular 4-vCPU EC2 instance.
Measure:
- CPU utilization
- Memory utilization
- Network throughput
- Disk throughput
- Disk IOPS
- Application latency
For example, a server currently using:
4 vCPU
8 GB RAM
Average CPU: 20%
Average RAM: 45%
might not need a large EC2 instance.
Conversely, a server with:
4 vCPU
8 GB RAM
CPU: 90%
Disk I/O: high
may require a substantially different architecture.
5. Migrating DigitalOcean Volumes to Amazon EBS
DigitalOcean Volumes provide block storage attached to Droplets. The AWS equivalent is generally Amazon EBS.

A simple migration is:
DigitalOcean Volume
↓
Temporary backup/copy server
↓
AWS S3 or transfer mechanism
↓
Amazon EBS
↓
EC2 Mount
However, you should first determine what the Volume contains.
If it contains application files:
/var/www/uploads
EBS may be appropriate.
If it contains:
images
videos
user documents
backups
Amazon S3 is usually a better destination.
If it contains a shared filesystem used by multiple servers, consider Amazon EFS or another AWS file-storage service instead.
6. Migrating DigitalOcean Spaces to Amazon S3
DigitalOcean Spaces is S3-compatible object storage. DigitalOcean explicitly documents compatibility with the S3 API and AWS S3 tools/SDKs.
This makes Spaces one of the easier DigitalOcean services to migrate.

The target architecture is:
DigitalOcean Spaces
│
│ S3-compatible transfer
↓
Amazon S3
Option 1 — AWS DataSync
AWS DataSync supports DigitalOcean Spaces as an object-storage location and can transfer data between DigitalOcean Spaces and AWS storage.
This is particularly useful for large buckets.
Example:
Spaces:
photos-prod
├── users/
├── products/
├── invoices/
└── backups/
↓
S3:
company-production-assets
├── users/
├── products/
├── invoices/
└── backups/
DataSync can also perform integrity validation during transfers.
Option 2 — AWS CLI
Because Spaces supports the S3 API, S3-compatible tools can be used.
For example, you can configure an S3-compatible endpoint for DigitalOcean and then copy objects to AWS S3.
Conceptually:
aws s3 sync \
s3://digitalocean-bucket \
s3://aws-s3-bucket \
–endpoint-url https://nyc3.digitaloceanspaces.com
The exact endpoint depends on your Spaces region.
Important considerations
Check:
- Bucket permissions
- Public/private objects
- Object metadata
- Content-Type
- Cache-Control
- Object ownership
- Lifecycle policies
- CDN configuration
- Application URLs
DigitalOcean Spaces uses an S3-compatible API, but compatibility isn’t identical to Amazon S3, so test applications that depend on provider-specific behavior.
7. Migrating DigitalOcean Managed PostgreSQL to Amazon RDS
This is one of the most important parts of the migration.
The target can be:
- Amazon RDS for PostgreSQL
- Amazon Aurora PostgreSQL-Compatible
AWS DMS supports migrations from self-managed PostgreSQL to RDS PostgreSQL and Aurora PostgreSQL. AWS also provides homogeneous migration capabilities using PostgreSQL-native tools.
A typical architecture is:
DigitalOcean Managed PostgreSQL
│
│ AWS DMS
↓
Amazon RDS PostgreSQL
PostgreSQL migration with pg_dump
For smaller databases, a dump and restore can be straightforward.
On the source:
pg_dump \
-h SOURCE_HOST \
-U SOURCE_USER \
-Fc DATABASE_NAME \
> database.dump
Transfer the dump to AWS and restore:
pg_restore \
-h RDS_ENDPOINT \
-U TARGET_USER \
-d DATABASE_NAME \
database.dump
This approach is simple but usually requires a write freeze during the final migration.
PostgreSQL Migration With AWS DMS
For larger production databases, AWS DMS can reduce downtime.
The general architecture is:
┌───────────────┐
│ DigitalOcean │
│ PostgreSQL │
└───────┬───────┘
│
│ Initial load
│
│ Change replication
↓
┌───────────────┐
│ AWS DMS │
└───────┬───────┘
│
↓
┌───────────────┐
│ RDS PostgreSQL│
└───────────────┘
AWS DMS can perform full-load and ongoing replication for supported PostgreSQL migrations.
The migration sequence is:
- Create the RDS database.
- Configure networking.
- Configure source PostgreSQL access.
- Configure DMS.
- Start full load.
- Allow changes to replicate.
- Monitor replication lag.
- Stop application writes.
- Wait for replication to catch up.
- Change the application’s database endpoint.
- Validate the application.
- Resume writes.
This can reduce the final downtime to the cutover period.
8. Migrating DigitalOcean Managed MySQL
The same general model applies to MySQL.
DigitalOcean Managed MySQL
│
│
↓
AWS DMS
│
↓
RDS MySQL / Aurora MySQL
AWS provides migration workflows for MySQL to RDS MySQL and Aurora MySQL.
For smaller databases:
mysqldump \
-h SOURCE_HOST \
-u USER \
-p \
DATABASE > database.sql
Then:
mysql \
-h RDS_ENDPOINT \
-u USER \
-p \
DATABASE < database.sql
For production systems where downtime matters, use replication or AWS DMS.
9. Migrating Redis
DigitalOcean Redis workloads may need to move to:
- Amazon ElastiCache for Valkey/Redis
- Redis-compatible infrastructure running on EC2
- Another AWS caching architecture
Please note, AWS Valkey might be cheaper than Redis.
First determine whether Redis contains:
Disposable cache data
If Redis is only caching database queries, you may not need to migrate the data at all.
Simply:
Create new ElastiCache
↓
Deploy application
↓
Application repopulates cache
Persistent application state
If Redis contains:
- queues
- sessions
- counters
- persistent application state
then you need a proper migration strategy.
For example:
DigitalOcean Redis
│
├── sessions
├── queues
└── application state
│
↓
migration/replication
│
↓
AWS ElastiCache
Do not treat Redis as disposable until you have confirmed exactly what the application stores there.
10. Migrating DigitalOcean Kubernetes to Amazon EKS
DigitalOcean Kubernetes and Amazon EKS both run Kubernetes, but they are not identical environments.
The safest strategy is generally not to copy the Kubernetes cluster itself.
Instead:
DigitalOcean Kubernetes
│
│ Kubernetes manifests
↓
Amazon EKS
│
├── Deployments
├── Services
├── ConfigMaps
├── Secrets
└── Ingress
Export or retrieve:
- Deployments
- StatefulSets
- Services
- ConfigMaps
- Secrets
- Ingress
- PersistentVolumeClaims
- CronJobs
- RBAC
- Helm values
Then adapt them for AWS.
Kubernetes storage
This requires particular attention.
DigitalOcean Persistent Volumes may need to become:
- Amazon EBS CSI volumes
- Amazon EFS
- S3
For example:
DigitalOcean PVC
↓
If block storage → EBS
If shared filesystem → EFS
If object data → S3
Don’t just recreate every DigitalOcean volume as an EBS volume.
11. Migrating DigitalOcean Container Registry to Amazon ECR
If applications use DigitalOcean Container Registry, Amazon Elastic Container Registry (ECR) is the natural AWS equivalent.
Example:
DigitalOcean Registry
│
├── app:v1
├── app:v2
└── app:v3
↓
Amazon ECR
│
├── app:v1
├── app:v2
└── app:v3
You can pull the existing image:
docker pull registry.digitalocean.com/myregistry/myapp:v1
Tag it for ECR:
docker tag \
registry.digitalocean.com/myregistry/myapp:v1 \
AWS_ACCOUNT_ID.dkr.ecr.REGION.amazonaws.com/myapp:v1
Authenticate to ECR:
aws ecr get-login-password –region REGION |
docker login \
–username AWS \
–password-stdin \
AWS_ACCOUNT_ID.dkr.ecr.REGION.amazonaws.com
Then push:
docker push \
AWS_ACCOUNT_ID.dkr.ecr.REGION.amazonaws.com/myapp:v1
For CI/CD, update the pipeline so future builds go directly to ECR.
12. Migrating DigitalOcean Load Balancers
DigitalOcean Load Balancer configurations should generally be recreated using AWS Elastic Load Balancing.
Depending on the application, you can use:
- Application Load Balancer
- Network Load Balancer
- Gateway Load Balancer
For a normal HTTP/HTTPS web application:
Internet
│
↓
Route 53
│
↓
Application Load Balancer
│
├── EC2
├── EC2
└── EC2
Instead of pointing DNS directly to an EC2 instance, point it to the load balancer.
This also makes future Auto Scaling easier.
13. Migrating DigitalOcean DNS to Route 53
DigitalOcean provides domain and DNS management as part of its networking services.
The AWS equivalent is Amazon Route 53.
Before changing DNS, recreate:
- A records
- AAAA records
- CNAME records
- MX records
- TXT records
- SPF
- DKIM
- DMARC
- Verification records
- CAA records
- Subdomains
For example:
DigitalOcean DNS
example.com
www.example.com
api.example.com
mail.example.com
becomes:
Route 53 Hosted Zone
example.com
├── www
├── api
└── …
Lower DNS TTL before migration
Several days before the cutover, reduce the TTL.
For example:
Before:
TTL = 3600 seconds
Migration:
TTL = 60 seconds
Then change the records to AWS.
After the migration is stable, increase the TTL again.
14. Migrating DigitalOcean Floating IPs
DigitalOcean Floating IPs provide static addresses that can be assigned to Droplets.
The AWS equivalent is generally an Elastic IP, although the preferred AWS architecture is often to put applications behind a load balancer rather than depend on a single public IP.
Instead of:
DNS
│
↓
Static IP
│
↓
One server
prefer:
DNS
│
↓
ALB
│
├── EC2
├── EC2
└── EC2
This eliminates a single server as a point of failure.
15. Migrating DigitalOcean VPC Networking
DigitalOcean VPCs provide private networking between resources.
AWS provides considerably more networking functionality through Amazon VPC.
A production AWS VPC commonly contains:
Internet
│
Internet Gateway
│
┌──────────┴──────────┐
│ │
Public Subnet Public Subnet
│ │
ALB NAT
│
┌─────┴─────┐
│ │
Private Subnet Private Subnet
│ │
EC2 EC2
│
↓
RDS
A basic production design often includes:
- VPC
- Public subnets
- Private application subnets
- Private database subnets
- Internet Gateway
- NAT Gateway
- Route tables
- Security Groups
- Network ACLs where appropriate
16. Migrating DigitalOcean Cloud Firewalls
DigitalOcean Cloud Firewalls are stateful network firewalls for Droplets.
AWS primarily uses:
- Security Groups
- Network ACLs
Security Groups should normally be the first layer you use for EC2.
For example, instead of:
Allow:
22
80
443
5432
from everywhere, create application-specific rules.
Web server
Inbound:
80 ← Internet
443 ← Internet
22 ← Admin IP/VPN only
Database
Inbound:
5432 ← Application Security Group
17. Migrating SSL/TLS Certificates
If certificates currently exist on DigitalOcean servers, decide whether AWS should terminate TLS.
A typical architecture is:
Internet
│ HTTPS
↓
Application Load Balancer
│
│ HTTP/HTTPS
↓
EC2
Use AWS Certificate Manager for certificates associated with AWS services such as Application Load Balancers.
This removes certificate-renewal tasks from individual servers.
18. Migrating DigitalOcean App Platform
If your application currently runs on DigitalOcean App Platform, there may not be a single AWS replacement.
Choose based on how the application works.
Containerized web application
Consider:
Amazon ECS + Fargate
Route 53
↓
ALB
↓
ECS/Fargate
↓
RDS
Kubernetes application
Consider:
Amazon EKS
Route 53
↓
ALB
↓
EKS
Event-driven application
Consider:
AWS Lambda
API Gateway
↓
Lambda
↓
DynamoDB/RDS/S3
Traditional server application
Use:
EC2
ALB
↓
EC2
19. Migrating Backups
Backups should be migrated separately from production data.
DigitalOcean backups may be useful for rollback during the migration, but they aren’t necessarily your long-term AWS backup strategy.
For AWS, consider:
- EBS snapshots
- AWS Backup
- RDS automated backups
- RDS snapshots
- S3 versioning
- S3 lifecycle policies
- Cross-region replication
For example:
RDS
│
├── Automated backups
├── Manual snapshots
└── AWS Backup
For S3:
S3
├── Versioning
├── Lifecycle
└── Replication
20. Migrating Monitoring
Recreate monitoring in Amazon CloudWatch.
Monitor:
EC2
- CPU
- Network
- Disk
- Status checks
RDS
- CPU
- Connections
- Free storage
- Read/write latency
- IOPS
- Replication
ALB
- Request count
- HTTP errors
- Target health
- Response time
Application
Use:
- CloudWatch Logs
- CloudWatch Metrics
- CloudWatch Alarms
- AWS X-Ray where appropriate
- OpenTelemetry-compatible observability tools
21. Secrets and Environment Variables
DigitalOcean applications may currently have secrets such as:
DATABASE_URL
REDIS_URL
API_KEY
STRIPE_SECRET
JWT_SECRET
SMTP_PASSWORD
Do not simply place all of them into EC2 environment files.
AWS provides:
- AWS Secrets Manager
- Systems Manager Parameter Store
- IAM roles
For example:
Application
│
↓
Secrets Manager
│
├── DB password
├── API key
└── OAuth secret
This also makes secret rotation and access control easier.
22. A Complete Example: Migrating a Laravel Application
Consider a DigitalOcean application with:
Droplet
├── Nginx
├── PHP/Laravel
├── Queue workers
└── Cron
Managed PostgreSQL
Spaces
└── User uploads
Redis
└── Cache + queues
Load Balancer
DNS
A good AWS target architecture would be:
Route 53
│
↓
CloudFront
│
↓
ALB
│
┌─────────┴─────────┐
↓ ↓
EC2/ECS EC2/ECS
│ │
└─────────┬─────────┘
│
┌───────┼────────┐
↓ ↓ ↓
RDS ElastiCache S3
│
↓
PostgreSQL
Migration sequence:
Step 1
Create AWS networking.
Step 2
Create RDS PostgreSQL.
Step 3
Start database migration.
Step 4
Create S3 bucket.
Step 5
Copy Spaces objects to S3.
Step 6
Create ECR repository.
Step 7
Push application image to ECR.
Step 8
Create EC2 or ECS infrastructure.
Step 9
Configure Secrets Manager.
Step 10
Deploy application.
Step 11
Point the application at RDS.
Step 12
Validate application behavior.
Step 13
Lower DNS TTL.
Step 14
Perform final database synchronization.
Step 15
Switch DNS to AWS.
Step 16
Monitor.
Step 17
Keep DigitalOcean available for rollback.
23. Testing Before Cutover
Create a formal migration test plan.
Infrastructure
Test:
- EC2 availability
- Load balancer
- Security Groups
- NAT
- DNS
- TLS
Application
Test:
- Login
- Registration
- Checkout
- Search
- File uploads
- File downloads
- Background jobs
- Webhooks
- API integrations
Database
Test:
- Row counts
- Critical tables
- Indexes
- Stored procedures/functions
- Permissions
- Transactions
Storage
Test:
- Object count
- Object sizes
- Permissions
- Metadata
- Application access
For example:
DigitalOcean:
users = 1,250,342
AWS:
users = 1,250,342
Then compare important business tables rather than relying solely on infrastructure-level success messages.
AWS notes that some homogeneous DMS migrations do not provide built-in data validation, so application and database-level validation remains important.
24. Common Migration Mistakes
Mistake 1: Treating AWS like DigitalOcean
AWS isn’t simply “DigitalOcean with more services.”
You need to understand:
- VPCs
- IAM
- Security Groups
- Subnets
- Route tables
- Availability Zones
- Load balancers
- IAM roles
Mistake 2: Migrating servers without understanding dependencies
A Droplet may depend on:
Droplet
├── PostgreSQL
├── Redis
├── Spaces
├── SMTP
├── DNS
└── External API
Moving only the Droplet doesn’t move the application.
Mistake 3: Forgetting background workers
Web traffic may work while:
queues
cron
scheduled jobs
workers
are broken.
Mistake 4: Forgetting object-storage URLs
Applications frequently store URLs such as:
https://bucket.nyc3.digitaloceanspaces.com/image.jpg
After migration, these may need to become:
https://cdn.example.com/image.jpg
or an S3/CloudFront URL.
Mistake 5: Changing architecture and cloud provider simultaneously
If your DigitalOcean application works perfectly, migrating it and completely rewriting it at the same time greatly increases risk.
A safer approach is:
Phase 1:
DigitalOcean → AWS with minimal changes
Phase 2:
AWS optimization
Phase 3:
Modernization

Conclusion
Migrating from DigitalOcean to AWS should not be approached as simply copying Droplets into EC2. The best migration separates data, compute, networking, storage, databases, DNS, and application services, then maps each workload to the appropriate AWS architecture.
The most important principle is to migrate state carefully and applications independently. Databases and persistent storage deserve the most attention because they determine how much downtime is required. AWS DMS can be particularly useful for supported PostgreSQL and MySQL migrations where continuous replication is desirable.
For large environments, a phased migration—discover → build AWS → replicate data → deploy → test → cut over → optimize—is generally safer than attempting a single large migration event.
