I would recommend that you upgrade the CAS/Hubs first. I would also recommend that you read this blog article from the Exchange team before deploying SP2.
http://msexchangeteam.com/archive/2009/06/12/451596.aspx We are not upgrading to SP2 yet since we also use an archiving product which is currently "Pending" support of their product used with this Exchange SP version. I suspect it is related to the named property changes referenced in the above article. Thanks, Peter Dahl.

I want to apply SP2. I have the procedure for the Cluster but I was wondering if should I apply the service pack to CAS/HUBS first, or after I apply it the Mailbox CCR cluster? Has anyone upgraded to SP2 yet? Any issues?
