I'm migrating my mailboxes (still) from old server to new server.
apparently, I can't migrate the mailboxes of accounts that are disabled (i have reason for not deleting the mailboxes).
what is best practice for those mailboxes?
Do i just leave them on the older server store?
or do I reactive the accounts and then move them over?
ASSUME that both servers are going to continue to run, just the new server becomes the primary.
Please advise what the best practices are.
