I faced the following issue and I couldn't find any help on net. So, I am posting the problem and solution.
When I restore a backup I get the following error:
"Your backup is from a different version of Microsoft SharePoint Foundation and cannot be restored to a server running the current version. The backup file should be restored to a server with version '4.1.10.0' or later."
I faced this problem after installation of October CU 2011 after SP1. I couldn't restore a backup of SPSite from a server with October CU 2011.
The issue was my webapplication was created before installation of October CU 2011. So, my schema was of Database was of previous version.
Solution:
Step 1: Delete your content database from central admin.
Go to Central Administration -> Manage Web Applications -> Manage Content Databases -> Select Your Web application -> select your content db. Delete it.
Step 2: Create a new content database from central admin.
Go to Central Administration -> Manage Web Applications -> Manage Content Databases -> Select Your Web application -> Create a new content database.
Step 3: Now restore the backup.
Now restore the backup through powershell or stsadm whichever is your favorite.
