We have a SharePointServer2013 installed with SQL Server 2014. But we need to restore site collection into another SharePoint2013 farm installed with SQL Server 2012. Any possible way to restore to Higher Version of Database.
At first you run Test-SPContentDatabase to see if you're missing fetures or site definitions. If you do, you need to install the solutions and site definitions that are missing.
Test-SPContentDatabase -name "wss_content" -webapplication http://sp76:2222 -ServerInstance "SP76"
When you have a successful run of Test-SPContentDatabase, you run Upgrade-SPContentDatabase, which will migrate the database schema of your content database to the 2013 farm schema.
When your database is upgraded, mount it using the cmdlet Mount-SPContentDatabase.
I have also received this error when attempting to mount a content database from one SharePoint 2013 farm to another. The issue in my case was the patch level difference between the source and destination farms.
If the destination farm is on a previous patch level, update the destination farm to the source farm patch level.
If the destination farm is on a newer patch level, update the source farm to the destination farm patch level before backing up the database to restore to the destination farm.
Hope this helps!
