ADMT, then Move Mailbox

Note:

When migrating to a new Exchange 2007 organization, use ADMT to migrate AD accounts first, then use move mailbox -- native in E2K7 (yay!) -- you do this through the Exchange Management Shell instead of the GUI -- to move the mailboxes from the existing org(s) to the new org.

I'm so happy things can happen this way. Another smooth move from the Exchange Product Group!
