Clean up nodes, databases, manifests
Once the migration is done and no regression is detected , clean up the leftovers:
databases (belvedere, bardo, ...)
puppet manifests with no longer required db instructions...
intermediary dumps used to shuffle data around
Some of those may already be done. Just make sure the rest is cleaned up as well.
