I've moved probably 20 single sites into my multisite network but when I hit this one I just can't make it work. I know you're not supposed to bring over users and usermeta but in this case it's necessary. The site has 112 members and I'm using Snapshot Pro to make the move. The backup/move seems to complete successfully but when I view the site none of the links work and all images are missing. When I look at the databases the imported members show up in the database of the new site and are not in the user database for the root site. I assume there are 1 or more gotchas with moving a membership site. What should I watch out for or do different.
