I just thought I'd bounce a question off you guys in regards to moving and upgrading Exchange 2010 Hybrid with O365 to Exchange 2013 hybrid with O365.
SBS 2011 with Exchange 2010
All mailboxes and Public folders have been transferred to O365
What I want to do:
I want to decommission the SBS 2011 server and move to Windows Server 2012 R2 (new DC). I want to keep password synchronization and I don't want to have to use attribute editor when creating users on-premise. So I will probably need to Keep exchange on-premise. In order to use Server 2012 R2, i need to upgrade to exchange 2013 and move Dirsync to my new DC.
I am aware that MS does not recommend installing Exchange 2013 on a DC
I was reading Exchange Deployment Assistant for my scenario and noticed that I still require ADFS + Exchange 2013 Client Access server and mailbox Role. All I really want is to be able to create a username on-premise and license it on the other side once it has been created... without having to modify the the AD account using Attribute editor(so mail enabled users). I won't need to create new on-premise mailboxes. I'm looking to see if I can do this without ADFS and make sure that Exchange 2013 runs very light(to conserve memory)
Have you guys had to deal with this situation? If you did do you have some references that I can look at? I can't find anything concrete online.
Any help would be appreciated! Thanks!
