Q: How do I move 5000 mailboxes (users named user1...user5000) from one mailbox database to another ?

A: Try one of the following one-liners in PowerShell:

1..5000 | foreach { get-mailbox "user$_" | move-mailbox -targetdatabase targetdbname -confirm:$false  }


get-mailbox -filter { Name -like 'user*' } -resultsize Unlimited | move-mailbox -targetdatabase targetdbname -confirm:$false

This is a little more efficient because it uses server side filtering and the multithreaded support in move-mailbox
