What is the best way to transfer the elastic disaster recovery replication servers/setup to a different region?

Let us assume that we have some source servers running on premise. We have already established DR using AWS Elastic Disaster Recovery into A region. What will be best way to migrate the DR setup to a different region B?

Hi, This is interesting. While AWS Elastic Disaster Recovery (DRS) doesn't directly support cross-region migration of DR setups, we can still accomplish it:
- Preparation and Planning: Assess your current DR setup, understand dependencies, choose the target region, and ensure compliance with data residency requirements.
- Setup Target Region Environment: Replicate the necessary infrastructure in the target region, including VPCs, IAM roles, and security groups. Install the AWS Elastic Disaster Recovery connector for on-premises sources.
- Configure New DR Policy in Target Region: Set up your disaster recovery policies in the target region, ensuring they meet or exceed your current setup's standards. Thoroughly test the new DR setup for reliability.
- Initiate Replication to Target Region: Begin replicating data from your source servers to the target region. Monitor the replication process closely to ensure data integrity and adjust bandwidth as needed.
Finally you have to think of migrating any data from Region A to B which follows the general data migration practices i.e S3 replication, Snapshot copy and so on.
Hope this helps.
