is there automation to migrate epics, issues, within a board to a new project

Hello @Mason Vieley 

Welcome to the community.

Do you really want the issues moved to different projects, or do you just not want the issues from all these different projects displayed in the one Kanban board?

Welcome to the Atlassian Community!

Moving an issue is not a trivial action, you could (and usually are) changing the whole structure of the issue.  It's not like moving furniture from one house to another, it's like converting a terraced house into a detached one.

There's no automation for anything but the most simple case of structural change (where two project/issue types have identical configurations)

You will need to use (bulk-)move - this can check all the configurations and take you through the most simple path for changing project and issue type without breaking anything.

You may note I did not mention boards.   They are an irrelevance here, a board is just a view of a set of issues, it's not a container.  The board may lose sight of the issues if you move them, and it may show you different information about them because you've had to change the data on them during the move, but the board doesn't matter for issue move.
