Hello,
I migrated to SharePoint 2013 from SharePoint 2010 recently in Dev and QA.
The issue is that we had classic authentication in SharePoint 2010 and claims based in SharePoint 2013.
I cannot convert the SharePoint 2010 to claims as its running in production and I don't want to touch that.
Now, I created a web app in SP 2013 using Central Admin and I guess its always claims based.
I attached the database from 2010 and upgraded it and the sites are all working fine. But as we know the user access is gone even though users can be seen in the groups on the upgraded 2013 sites.
I read about changing the superuser accounts in SP 2013. But I am confused. Can someone please mention the exact steps to resolve it, I earnestly request not to send me links to MS Technet articles or blogs but give me the steps here if its possible. Thanks in advance
