I'm using the following Amazon EC2 resources in the US East (Virginia) region:
- 1 Running Instance
- 1 Elastic IP
- 2 EBS Volumes
- 100 EBS Snapshots
- 1 Key Pair
- 2 Security Groups
- 5 My Own AMIs (customized based on my application stack)
My instance is based on Linux distribution (CentOS) and my AMIs are S3-backed. Both EBS volumes are mounted on this running instance.
We're planning to migrate our deployment to US-West region. Because Amazon EC2 resources are not shared across regions, my questions are:
- What are all the factors that I need to consider in advance?
- What are all the recommended & different ways of migrating each EC2 resources from one region to the other?
- Are there any hidden risks involved during and/or after the migration?
Experts ideas/suggestions/recommendations on this are highly appreciated.
