I have a client with an existing Exchange 2007 organisation with approximately 200 users, all with reasonable size mailboxes. They wish to move to a new Exchange organisation in a completely new AD forest, on new hardware, in a different physical location. This new network is allready setup and waiting for use.
My question is, what is the best way to move these mailboxes to the new organisation? I fear I may need to use Export-Mailbox to export all these mailboxes to PST files, FTP them to the new location, create Mailboxes for every user and then re-import the data, which will be a very time consuming job, so if anyone has any better strategies, or tools to help they would be very much appreciated.
Even if there is no easy way to move the mailbox, do you have any recommendations to easily move AD accounts, even if the data has to be imported separately.
