I am currently running Exchange 2013 CU2 on Server 2012 in Hyper-V. It seems that whenever I do an upgrade several things happen to the Exchange 2013 CU2 installation.
1. Without doing a repair to exchange, the Exchange Powershell is no longer available
2. The Exchange Mailbox Database becomes corrupted from a dirty shutdown if it is not dismounted first
3. The Mailbox Database will not mount after the upgrade, even after doing a repair on Exchange 2013 CU2
I have tried everyway I can think of to get this to work, but for some reason the upgrade must either remove necessary services or features.
I have done an in place upgrade, this corrupted the database, and the database after being repaired would not mount.
I have stopped all Exchange 2013 services, after upgrade the database still wouldn't mount
I tried dismounting the database and stopping the exchange services, database still wouldn't mount.
In all instances the Exchange 2013 installation was changed in some way, as stated before the Exchange Powershell was no longer available, and I am not sure what other items may have been changed.
I was receiving ExchangeIS errors, which I understand were from authentication, and these made sense since the database was down.
Anybody else tried this upgrade and had any success?? I really would like to know why the server upgrade does anything to the Exchange installation or the Mailbox Database, and what if any services have changed or been added in R2 that would cause these issues.
Any insight would be greatly appreciated.
