After Mount databases every path links /sites broken, what can I do to fix it?
In the farm there is only standard link path /sites, no custom path?
Even we faced the same issue when migrating from 2007 to 2010. It was rectified when the port of 2010 environment was set to be same port number of 2007. I am not sure why and how it solved the issue but can any one of SharePoint experts out there can shed some light onto it?
