Hi All, Need some advice on Ex07/10/13 co-existence + upgrade. I have multiple EX servers in multiple locations, most running EX07, one running EX10 and I have recently installed 2 new EX servers running EX13.
All on the same domain but in different locations, connected via private network. I have followed the co-existence install and updates on all current EX servers and on the first EX13 server all installed OK. AD has been prep'd and schema updated, etc. All fine.
With the 2nd EX13 server (which is in a different location from the first EX13 machine.) I have installed via the CU2 setup.exe and EX is installed successfully.
However I ran into issues when trying to login to EAC on the 2nd EX13. Everytime I tried to login as admin it would re-direct to OWA for the admin account. The Admin mailbox is located in the first EX13 server. And I tried all the other EAC and ECP urls, none work.
So do you need an admin account + mailbox on each EX13 machine to manage it? Sounds a bit odd. I would have thought I could manage all EX13 machines with the 1 admin account. Eventually I created a new mailbox on the 2nd EX13 machine from the 1st EX13 machine, applied the EX admin permissions and then could login to EAC on the 2nd EX13 machine and manage it. So currently I am using 1 login to manage EX13 1st machine and another admin login to manage EX13 2nd machine. is this right?
Thinking this may not be correct I then reinstalled exchange with the prep AD and prep schema switches.
This fails and says the server cannot contact the schema master and it needs to belong to the same site, etc. I didn't think I had to run prepAD again as the domain has already been prep'd for EX13 and the first machine is currently up and running ok.
Currently the 2nd EX13 seems to be working ok, I have moved mailboxes between servers and got mailflow working.
Have I installed this 2nd EX13 machine correctly though? Thanks in advance.
