Oh, There was one bit of housekeeping I did before the upgrade.
I cleaned up my forum structure meaning deleted old forums not needed and moved the posts to valid forums.
Cleaned up my member database some by deleting what I determined to be non valid users.
With that in mind you probably know this already. But nobody can be member #1 it will be reserved for anonymous users.
