I had a WSS3.0 instaliation with forms based authentication, and I wish to migrate to SP2013. I have SP2010 and SP2013 servers, I've successfully detached content database from WSS 3.0, attached to SP2010, detached and atached to SP2013, performed following:
Convert-SPWebApplication -Identity http://Your-Server-Name -To Claims -RetainPermissions
It renamed all the users in UserInfo table to "i:0#.f|provider|", but kept the old names (provider:) in all metadata:
- documents author, modifiedby (this is not a big issue, I wrote a script to fix it)
- documents version history, same situation, problem is that versions are read only from API/powershell side.
Has anyone else faced this situation (I guess there should be many people with same problem, just wondering why I can find any solutions on internet).
