Same here. As far as I can tell, the Groupwise migration tool for 4.5.6 is pretty much useless. I tried using the BETA2 tool, but it is incompatable (not surprisingly) with 4.5.6 server. We might just have to wait until this winter (break) and migrate to Zimbra 5.0. It is getting too close to the start of the next semester.
