I have a SharePoint 2010 instance (QA) that had been working. Now when I try to migrating and mounting a content database (or configuration database) I am getting an error and the database is not loaded.
The error I am getting in PowerShell is:
There is a compatibility range mismatch between the Web server and database "", and connections to the data have been blocked to due to this incompatibility. This can happen when a content databasse has not been upgraded to be within the compatibility range of the Web server, or if the database has been upgraded to a higher lever than the web server. The Web server and the database must be upgraded to the same version and build level to return to compatiblity range.
I am working with both SP2007 and SP2010 environments. Using SQL Server 2008. This problem occurs wheather I am trying to mount a SP2007 (conversion) or SP2010 content database. The SQL Server 2008 versions and builds are the same on all SP2010 environments.
I would appreciate any help resolving this issue.
