I am mid-way through a project. We have decided it was necessary to rebuild our SharePoint 2010 environments. Due to a lack of resources we decided to utilize the same SQL Server for the new environment as the old, meaning temporarily we have 2 farms running from one instance of SQL. Everything has gone fine until now. I've made a copy of one of the content databases from the original environment, and restored it to another filename, and am trying to attach it to the new Sharepoint farm. It is not recognizing any of the site collections in it.
I have verified that the 2 farms are on the exact same version. And to make sure this is clear when I say two farms; I mean we have to completely distinct config db's running on the same instance of SQL. So this should remove the possibility of GUID conflicts... shouldn't it?
