Roll back migrated mailbox to exchange 2016
Hi all, I want to roll back a migrated mailbox from exchange 2019 to 2016 is this possible ? what to consider ? currently migration of 2016 to 2019 works without errors.
There should be no issue migrating the mailbox to a mailbox DB located on the Exchange Server 2016 server as long as everything is configured correctly for co-existence.
- it seems there are some Mailbox Attendant issues where I can see related Arbitration Mailboxes for 2016 but cannot find it for exchange 2019 servers. I'm not sure if I must see another arbitration mailboxes for 2019 or not. but I'm sure this is the current problem.
- Part of your migration to Exchange Server 2019 is the migration of all arbitration and system mailboxes to a DB on the new server(s). This blog might help if you haven't done that https://www.alitajran.com/move-arbitration-mailboxes-in-exchange-server/
- If the migration now is working from 2016 to 2019 you can move back without impact ....
