Upgrade three 2008 (non R2) servers (2 has EX2010) to 2012 R2...
All x64, all with latest updates. One Exchange has SP2 (KB2903903) and doesn't (some error when I tried.)
Keeping the Exchange as 2010.
Just straight upgrade installation on all 3 servers? PDC, BDC, then the server?
Or am I asking for trouble?
Oh, the PDC has 2 SATA HDs that are mirrored by OS on C: and D:. What a nightmare last week when it failed to reboot with a FTDISK_INTERNAL_ERROR Stop Code 00000000x58. I really need to do away with OS raid 1 and 2008 server.
Maybe add a 2012 R2 + exchange and move all the services over and demote the old raid 1 server?
When I was a T3 Exchange Escalation engineer for Microsoft, I wouldn't even talk to you after I found Exchange was installed on a DC.
Do it correctly this time and you won't have to do it again and you will have far less issues.
