We are thinking of patching Exchange 2007 SP3 on 2 CCR clusters (Windows 2008 SP2), and wonder if you can provide me with best practices, step by step guidelines to deploy it on CCR.
My understanding is we should start patching the passive failover, reboot it, and then failover to passive node, and path the other node. Mi problem is I must patch the passive node on business hours 6PM EST, but the active node must be patched after business hours 5 hours later. Is there any problem with this?
Any advices, best practices for patching CCR, recomendation would really appreciated
Thank you in advance
