While restoring a database from one farm to other I encounter below error:
Mount-SPContentDatabase : This content database has a schema version which is not supported in this farm
When I check the version of current SharePoint and restore database version they were different.
You can check current SharePoint version as follow:
Go to Central Administration -> System Settings-> Servers-> Manage Servers in the farm.
You can check the version of the database in version table of content database.
You can check SharePoint build version here.
You need to install updates in your new farm and when your SharePoint and database version are same you can Mount database to new farm.
