I'm upgrading from 2010 to 2013 and when I ran the Test-SPContentDatabase (on destination WFE server pointing at original content DB) command I got the following error relating to an orphan site:
Database [WSS_Content] contains a site (Id = [8579eb01-ea17-4192-81e1-1e3aaba99aed], Url = [/]) whose url is already used by a different site, in database (Id = [d6fd0486-081e-4e0d-aba8-d8816b606a2d], name = [WSS_Content]), in the same web application. Consider deleting one of the sites which have conflicting urls.
Things I have tried:
- Detaching and attaching the content DB using PowerShell
- Running STSADM DatabaseRepair command
- Running STSADM Enumallwebs command
I prepped the new 2013 WFE server by creating a temp Web Application which uses Windows authentication (will convert to CBA post-upgrade). There is also a top level site collection on the 2013 server and I'm wondering if this is the cause? I have tried all the conventional approaches I can think of and checked similar questions here.
UPDATE - 11/18/2013:
I ran a SQL script on 2010 content DB to locate duplicate site [d6fd0486-081e-4e0d-aba8-d8816b606a2d] and got no results. When I ran it on the 2013 DB I got a result in the WSS_Content DatabaseInformation table which looks like the root site collection? Does this mean I should delete the destination 2013 site collection before proceeding with the upgrade?
