We are doing a migration from a domain to another (inter forest) We have about 200 heavy users (large mailboxes, Autocad, 3DSMAX...)

We've been using the move-mailbox cmdlet so far.  But is there another cmdlet that could be used to migrate users in batches ?

BTW, ADMT 3.1 is a great tool, very useful and easy to use.

Not sure if this qualifies...but Exmerge, while it  will not move file directly will, through its menu export each mailbox to .pst (one command) then import each .pst back in.

If you want to increase the the number of users that you move at a time (default is 4), you can use the MaxThreads parameter in move-mailbox cmdlet.

eg; Get-Mailbox Database DCEXCH\First Storage Group\Mailbox Store (DCEXCH) | Move-Mailbox TargetDatabase E2K7\First Storage Group\Mailbox Database MaxThreads 10

Check http://www.msexchange.org/articles_tutorials/exchange-server-2007/management-administration/moving-mailboxes-exchange-2007-part2.html

Towards the end of the article, it describes what you need.

I'm not sure I can use Get-Mailbox from a forest to another.  In the article it's about the same forest.

You can use move-mailbox cmdlet for cross forest migrations.

move-mailbox will work across forest and it can be combined with the get-mailbox to automate it in batch


it is enough to specify the source credentials and global catalog

everything you need to know is in that article
