Planning
During the phases of your migration project, review these best practices to help you to a successful outcome.
-
Plan your Migration project prior to installing the AWS Replication Agent on your source servers.
-
Do not perform any reboots on the source servers prior to a cutover.
-
Do not archive or disconnect the source server from AWS until your launched cutover instance in AWS is working as expected.
Testing
-
Perform test at least two weeks before you plan to migrate your source servers. This time frame is intended for identifying potential problems and solving them, before the actual cutover takes place. After performing the test launch, validate connectivity to your test instances (using SSH for Linux or RDP for Windows), and perform acceptance tests for your application.
-
Ensure that you perform a Test prior to performing a cutover.
