I am planning to update my Exchange CU10 -
currently I have physical DC (2008 r2) and virtual Exchange. Exchange roll up talks about backing up Exchange and DC before upgrade. For virtual Exchange I can take snapshot or use VDP based backup, however, for physical DC and DHCP server I do not have any third party backup. What I is the recommended backup before I try CU update on Exchange.
Since I am planning to introduce 2012 virtual DC in my environment. Would it be better to install virtual DC in my environment take a snapshot of that and then plan exchange roll up?
