Concerning rebooting or updating Exchange 2007 CCR, I always heard about moving Exchange cluster but what about Windows cluster? Do we need to take care of it? Does it suppose to move at the same node as Exchange cluster? (If yes, does Windows cluster should be moved first?).Thank you.

Moving Exchange group is important and which should be done throughMove-ClusteredMailboxServer so exchange closes all transaction gracefully. Windows cluster group or quorum owner is not important and it can stay on passive node also and when Windows reboots cluster service will take care of moving it to alternate available node...

Yes! Exchange group is important because it has to take care of all transaction logs and it takes more time comparatively. also it should not be done from Cluster admin. Since cluster group does not take much time (few Seconds) as it just need to change ownership of the quorum, it is not required to move that manually. The order also does not matter. cluster service will take care of it automatically when the quorum owner is down. Vishal Ramnani | MCITP - Exchange 2007 | MCSE Messaging | MCTS - Win 2008 Config

Thanks for the answers so I suppose moving Windows cluster and Exchange cluster on the same active node is more necessary if we do Windows updates for exemple. Is that right?

Still not, because Cluster service will take care of Windows Cluster group to move to passive node automatically. More important is Exchange cluster group because while windows update restarts windows, it will inform cluster service which takes care of windows cluster group while cluster serive or cluster admin is NOT Exchange aware so it does NOT take care of Exchange transaction log closer graceful and shutdowns...Amit Tank | MVP Exchange Server | MCITP: EMA | MCSA: M | http://ExchangeShare.WordPress.com
