Automatic mailbox distribution

Question

When our Exchange environment was setup a few years ago, we created one database per internal company. We have a script which creates mailboxes for new employees for primary company and in the script we specified the database to avoid the new accounts
from randomly being placed in the other company databases.
I need smaller databases to make recovery easier, so I've created additional databases on a separate local LUN. Our primary database LUN has 96GB/835GB free, and the secondary LUN has 632GB/835GB free. This is after moving about 100 mailboxes to another
db on the secondary LUN but without cleaning up the whitespace on the primary db.
While researching something else yesterday, I see that Exchange 2010 has auto mailbox provisioning, but it seems as if it will only auto provision if the mailbox is created without specifying the mailbox name, or when performing a local move request without
specifying the destination filename. I have now excluded the non-primary company databases from provisioning.
Would the easiest way to auto provision all the mailboxes for the primary company be to perform a new local move request for some/all of the included mailboxes without specifying the target mailbox and then consider an offline defrag?
Thanks,
Jim

Hi Jim,
From your description, I would like to clarify the following things:
1. If you don't specify the target mailbox, it will auto provision all the mailboxes.
2. If you just want to move mailboxes, I recommend you use Get-Mailbox instead of using Get-Recipient. The second one will get all the mailboxes, distribution groups, mail contacts, not only the mailboxes.
Hope my clarification is helpful.
