After you have launched your test instances, open the Amazon EC2 console and SSH or RDP into your test instances in order to ensure that they function correctly. Validate connectivity and perform acceptance tests for your application.
If you encounter any issues and want to launch new Test instances, or if you are performing a scheduled test and plan to perform additional tests prior to cutover, you can revert the test. This reverts your source servers' Migration lifecycle status to Ready for testing , indicating that these servers still require additional testing before they are ready for cutover. During a revert, you also have the option to delete your Test instances for cost-saving purposes.
To revert a test:
-
Check the box to the left of every source server that has a launched Test instance for which you want to revert the test.
-
Open the Test and cutover menu.
-
Under Testing, choose Revert to "ready for testing".
-
The Revert testing for X servers dialog appears. Select whether you want to terminate the launched instances used for testing. It is recommended to terminate these instances, as you will be charged for them even though you no longer need them. Check the Yes, terminate launched instances (recommended) box and choose Revert.
The AWS Application Migration Service console indicates that testing has been reverted. The selected source servers' Migration lifecycle column shows the Ready for testing status, the Next step column shows Launch test instance and the launched Test instances are deleted if that option was selected.
