Preventative measure for Exchange Server Windows & Service Pack patching
Posted on 2015-01-31
I'm currently planning to apply the Exchange Server 2010 Service Pack 3 and also applying the Cumulative Update 7 along with Windows Update which haven't been done since the past two years (~110+ patches).
So in this case it I cannot afford to lose any of the Exchange Server due to the bad update or broken server due to patches. It is currently running on VMware VM with the following details:
Mailbox Server stand alone non-DAG:
My questions are:
1. When taking the VMware snapshot for easy rollback, do I have to take the entire 3 sets of the domain controller as well ?
2. Assuming I have done the Schema Update successfully and moving on to apply the SP3 to the HT/CAS server role, do I have to take both of the mailbox server VMs snapshot as well ?
If anyone has a better way to quickly roll back broken Exchange server due to patching, please sahre it here.
