GW 8.0.2 HP2 on NetWare 6.5 SP8 and SLES 11 64-bit

I am moving 2,000 users from my NetWare post offices to my new SLES post offices. Currently, there are about 1,000 users per post office (yes, it is working... barely). I will be splitting up the users into the four new post offices. Any suggestions on the best way to get this done? I don't think I can use the migration utility. Am I destined to manually move each user?
