Depending on the IT policy on the BES that will get pushed down, and what your BES set up is like (may include Over-the-air backup), you'll want to restore the data
after the wipe but
before activation. Since depending on your set up, some data cannot be restored once server-sync is set up for some items. The
Desktop [SYNC] service book will prevent this (or some) data from being restored using BDM.
See the following for information on what is not backed up OTA.

What types are data are we talking about? Be specific.
Restoring email messages (At least on Domino, is a little problematic. In some cases (depends on the state database and planetary alignment) reconciliation of deletes for the restored messages (prior to reactivation date) will not always work. Sometimes it's only reconciling of deletes of old messages (prior to reactivation) from the handheld do not always reconcilate to the server, but from the server to the handheld works fine. Othertimes it's the other direction that won't reconcile. Somes most of the old messages will reconcile, but a few won't. It varies for user to user. This is when restoring old messages prior to reactivation. So I don't do it anymore. I just delete the user, and let 750msg/14day prepopulation do it thing and tell the user to move on. It's just not worth the support call for me).
I also don't bother restoring PIM data that is synchronized to the mail server via BES. I just let that come down (message propopulation, address book, calendar, memos) during activation.
I would do the following (this may change depending on any additional information you provide!!)
1. Backup the devices via BDM.
2. Wipe the devices.
3. Restore the following data using BDM on the fresh devices.
3a. call logs (since we're deleting the server from the BES)
3b. options " "
3c. profiles " "
3d. autotext " "
3e. content store (in case user has pictures from the camera in device memory like my CFO did!)
3f. SMS text messages (if needed)
3e. memos (if not sync'ed with mail server OTA)
3g. address book (if not sync'ed with mail server OTA).
4. Delete user from BES (if this were domino, we'd also delete the state database).
5. Re-add user to the BES. Set Activation password.
6. Perform Enterprise Activation from the handheld.

On restoring old messages, RIM has the following information. I don't recommend it, since based on what we've seen on Domino, reconcilation doesn't always work for the old messages. But sometimes you run into that C-level executive that just has to have than random 91-day old email restored to his/her new handheld. C-level executives (or their secretaries) rarely listen to reason, so here you go...
