Thanks MBS. It's in the release notes for SP3. It was actually there for SP2, too:
http://technet.microsoft.com/en-us/library/jj965774%28v=exchg.141%29.aspx#BKMK_DatabaseSchemaUpgrades I'm trying to think of a situation that would even let this happen. The best I can think of is if you want to retrospectively add (or try to add) a database copy that's seeded from an SP3 server to an SP2 or earlier server. Otherwise, if you upgrade MBX1, which subsequently fails before MBX2 has been upgraded, then MBX2 still has SP2 schema databases and stays happy. Right? :) From: bounce-9582527-8066...@lyris.sunbelt-software.com [mailto:bounce-9582527-8066...@lyris.sunbelt-software.com] On Behalf Of Michael B.

No, the upgrade dismounts the databases on the current copy. Which should all be passive.

What I want clarified is the database schema upgrade: "During the upgrade, the database is dismounted, and all mailboxes in that database are taken offline." Now I'm almost certain that in a DAG environment the mailbox server that is now hosting the active copies of the databases will not dismount all its databases. This is an extremely confusing statement imo. Anyway, I'm testing this now in a lab. --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com<mailto:listmana...@lyris.sunbeltsoftware.com> with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com<mailto:listmana...@lyris.sunbeltsoftware.com> with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist
