Good Morning,
We are deploying Exchange 2013 CU 14 as a hybrid server to replace the existing Exchange 2010 hybrid that is in place at the moment. As part of the Exchange 2013 installation, I need to prepare and update the AD schema for the additional attributes required
by Exchange 2013.
I have a process detailed on how this will play out but have questions around using snapshot in VMware as a recovery method.
The forest contains three domain controllers and the DC upon which the changes will be made is the least utilised and will have replication inbound and outbound disabled prior to running the PrepareSchema and PrepareAD switches on the Exchange setup.exe.
My question is whether the snapshot would be a supported method of rolling back the DC in the event of the schema update causing corruption? The forest contains services such as System Centre which are sequence sensitive and my concern is that by rolling back the snapshot, we may introduce problems with USN's and sequence sensitive processes. There will also be BMR, System State and Service Database backup's taken immediately before but I'm ultimately trying to avoid having to invoke forest recovery by hopefully using the snapshot.
