SharePoint Troubleshooting: Your backup is from a different version - Error while restoring the site
Error
Restore-SPSite: 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 '4.2.7.0' or later.
Resolution
First, check the patch level of your source and destination environment. Make sure your destination environment is not at a lower version than the source. If so, you may need to patch your environment as same as your source.
Steps to Check Database Schema Versions:
Central Administration application > Management > Manage content databases. Select the database where you want to restore. Click on the DB name under “Database Versioning and Upgrade”. You will see something like below:
Microsoft.SharePoint.Upgrade.SPContentDatabaseSequence Current Schema Version: 4.1.30.0, Maximum Schema Version: 4.2.7.0
Microsoft.SharePoint.Upgrade.SPContentDatabaseSequence2 Current Schema Version: 4.1.7.0, Maximum Schema Version: 4.1.7.0
Microsoft.SharePoint.Administration.SPContentDatabase Current Schema Version: 14.0.6137.5002, Maximum Schema Version: 14.0.7105.5000
If the Current Schema Version is less than the Maximum Schema Version, then the database should be upgraded as soon as possible.
To upgrade the content database, execute the command below in PowerShell:
“Upgrade-SPContentDatabase <Content_db_name>”
After executing the command:
Microsoft.SharePoint.Upgrade.SPContentDatabaseSequence Current Schema Version: 4.2.7.0, Maximum Schema Version: 4.2.7.0
Microsoft.SharePoint.Upgrade.SPContentDatabaseSequence2 Current Schema Version: 4.1.7.0, Maximum Schema Version: 4.1.7.0
Microsoft.SharePoint.Administration.SPContentDatabase Current Schema Version: 14.0.7105.5000, Maximum Schema Version: 14.0.7105.5000
Now the database is upgraded to the version 4.2.7.0 and you can restore without any issues.
