Hi what order should I uninstall our exchange 2007 estate now we have moved to exchange 2010? we have hub, cas and CCR mailbox roles I was thinking mailbox (not sure I need to remove or just shutdown passive CCR node), then CAS and finally hub thanks Jez

I would recommend uninstalling the mailbox roles first. Here is a great article to walk you through uninstalling the CCR environment: http://exchangeserverinfo.com/2009/09/24/uninstalling-exchange-from-clustered-environment--ccr.aspx Then uninstall the HUB and CAS. Doesn't really matter the order, if on same server, do them at the same time.Tim Harrington - Catapult Systems - http://HowDoUC.blogspot.com

Per my knowledge, there’s no official document for the exchange 2007 server roles’ removal order Please make sure that all services are not requiring exchange 2007 server to function, like mail flow (HT), client access (CAS), public folder (MBX) Tim’s suggestion is an option James Luo TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Well, it would almost be the opposite of the installation order :) I agree with Tim and JamesJonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog
