Follow your Migration Project Plan for the steps you defined to remediate gaps, deprecated features, and any other required application changes. Additional issues may be uncovered during this phase, so thoroughly test your application in accordance with your testing strategy.  Continuously update the testing strategy with new test cases, as needed.  Follow the testing strategy in each assessment phase for steps on remediating gaps and addressing deprecate features and functionality, as needed.

If you identify types of issues that require remediation that are not currently included in the tools and documentation provided by Pega, provide information about them to your Pega account team. Your Pega account team can pass on the information to the appropriate teams at Pega, so that Pega can assess including information about those issues when updating the tools and documentation.
