Migrating 100 phones to ABM

Hi,

We have just signed up for and imported 100 phones into ABM. We have a 100 existing users who have all signed up to various iTunes accounts (some using the company domain, some not) which we need to migrate into ABM.

Has anyone done this before? If so is there a less painful method of doing it other than messing around with full itunes backups and resets of phones? I am guessing the restore bit will not be easy if the backup was taken from a different iTunes account to the restoring itunes account?

Any help greatly appreciated.

Bump - does anyone have any idea's on this please?
