Remove / Re-Install Exchange 2013 with Exchage 2007 still active
Posted on 2016-10-16
I recently picked up a client who is ready to migrate to Exchange 2013. However the prior I.T. company started the Exchange 2013 install almost a year ago but stopped just after installation (no mailbox moves) due to another project the company had going. The physical server they built the VM on is not sufficient. Also the owner wants to have Exchange on it's own physical box.
So here are my questions
1. Should I remove the currently installed Exchange 2013 before installing the new Exchange 2013 server.
2. If yes will removing the HealthMailboxes from Exchange 2013 affect the Exchange 2007 since they now show up in Exchange 2007
3. Or should I install the second Exchange 2013 and move the Arbitration mailboxes to it then uninstall first Exchange 2013 server and continue the migration.
