I just did a test import from 6.5 to 7.5 and I see 2 issues so far.

I all the users of the board now are listed as Moderators or at least under Group Management there are now over 7200 Moderators.

I think had to go through every forum and fix the permission because a lot of them there was no values in the field. So I had to enter either a 1 or 0 into the field. Once I was done with that I tested a few of the members accounts and they could not see any of the forums. All I was getting the message "There are no forums for you to view." .

All message and forums imported over fine. I can log in as one of the Admin users and see everything. I double checked all the permisson give access to see the forums to all groups but that did not change a thing. I still can not view any forums.

I've seen this happen on a few imports. If you can open up a support ticket with the admin info to your test forums we can take a look and should be able to get it resolved for you.

I recently went through the exact same thing...you set permissions in the "forum settings" as well as the "group managment" screen...and all my members imported as moderators [over 10k of them!].
