This request is for the JCMA migration tool to allow for the selecting or exclusion of some boards that are not needed in the cloud to reduce the amount of post-migration cleanup and for other reasons they have.

1. JCMA doesn't include which boards will be migrated; post-migration it's a manual comparison of boards per project.
2. Alternative approach to migrating boards and filters in the event of errors.
3. Offer some options to mitigate the errors found and steps to follow to ensure the migration works in the first place. The sheer number of projects being handled makes this cumbersome to investigate.
