Remove / Re-Install Exchange 2013 with Exchage 2007 still active
Hello,
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.
Thank you,
Leon

You'll want to uninstall Exchange 2013 on the server the other guys put up at some point, preferably before migrating mailboxes. The arbitration mailboxes can be removed, since they are tied to that specific server, or you can put up the new 2013 server and move them to it. It shouldn't make too much of a difference which one you choose. If you choose to delete the Arbitration mailboxes, make sure to do so *before* installing 2013 on the new server, though, since they may cause issues if you install 2013 and then delete the arbitration mailboxes (They may get assigned to the new server's use, which can cause some headaches. This has happened to me before and it takes a lot of effort to fix).

Adam,
Thank you for the info. I believe I will go ahead and remove the current Exchange 2013 box before spinning up the new one. My main concern was removing those arbitration mailboxes, since they show up in the Exchange 2007 console. Was not sure if I needed to migrate them or if I could just remove them then uninstall Exchange 2013. Don't want to break the current mail server.

Thank you all for your help and input. I decided to follow Ivan and Simon and spun up the new Exchange 2013 server, I then migrated the Arbitration and discovery mailboxes to the new server.
Once that was done I uninstalled the original Exchange 2013 server with no issues. Again thank you all for your help, I don't have much experience in multi exchange environments and just wanted to cross my "t" and dot my "i" as it were.
Now on to the rest of the migration.

So ignore the current Exchange 2013 server for now and do the normal migration to the new server. What about Arbitration mailboxes that are on the incomplete server / database can I just remove those and delete that database without messing anything up or will I need to migrate those to the new Exchange server?
Thanks,
Leon
