Exmerge will kill his single instance storage, and his 40GB database will
end up at almost 50GB if he's got only a 1.2:1 ratio. I'd try moving the
mailboxes in chunks of 50-100 at a time, and ensure that it's done from the
receiving server's Admin program for efficiency.
I'd guess that this can be done in 2-3 working days, without overtime. Just
let the users know that their mailboxes may be "temporarily inaccessible"
and that their access should be resolved in 20-30 minutes (it should take
less per mailbox, but you always look good when things take less time than
you've said...).

Sander,
Any reason you think that exmerge will bring along corrupted messages ?
Since Exmerge is essentially copying the message from the mailbox store to
the .PST file, a corrupted message will cause Exmerge to hiccup.
We had major store corruption some time ago, approx 600 of the 1600
mailboxes wouldn't move via the Exchange Administration tool due to
corruption. Exmerge allowed those mailboxes to be successfully moved. Simply
looking at the exmerge log file, deleting the offending message(s) from the
mailbox allowed the migration to occur in most cases.
We have also used Exmerge doing only the first phase of the migration
(extracting to .PST file), in order to determine which mailboxes were
corrupt. Have done this a few days ahead of a migration to determine those
mailboxes which will have to be manually moved. This allowed us to expedite
those mailboxes with no detected corruption, and focus our efforts on those
mailboxes that were having problems.
