I was unable to upgrade from SharePoint 2010 to SharePoint 2013 because I getting the following error when run the Site Collection Health Check:
you need to fix the following problems before upgrading:
missing Site Templates
the following sites are using templates that are not yet supported after upgrade:
.http://servername/samples/projectSite - #0
sites that rely on these templates can't be upgraded at this time, preventing upgrade of this site collection
can someone please help?
Thanks.
