Your backup is from a different version of Microsoft SharePoint Foundation

I got this error while restoring a backup taken from my Dev server onto QA server.

The error was "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 ’14.0.0.4762′ or later"

After googling for many hours found some solutions

1. In Central Admin, go to "Upgrade and Migration".  Click on "Check product and patch installation status".  Scroll down the page of results and see if there are any links to updates that have been installed on the original server that are not on the new server, or vice-versa.
If you find different versions then update the hotfix on the other server. after updating make sure both server's versions are same.

Then I tried to restore again.
 This time I got "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 '4.0.145.0' or later.""

Then again googled found this article

Thanks to author

the reason is, though foundation is update to date, content database is still not upgraded to new version. To ensure follow these steps

1. Check The DB schema
Get-SPContentDatabase <DB name>| Format-List *
In this check the SchemaVersionXML if it is "4.0.145.0" then you have to run the below powershell script
2. Upgrade-SPContentDatabse –Identity <DB Name>

Then I tried taking a fresh backup and restoring. This time its SUCCESSFUL . I Used STSADM to do this
This one helped me to resolve the problem which I faced.


For your info:- To ensure the versions in both servers.  Open the target application's content database in both servers then find a table called "VERSIONS". Then query the table and find the versions that web application using. it shows both versions of Foundation as well as content databse version. DO NOT try to change anything here.
