Question:A vendor sent me some detached MDF files from a SQL Server and asked me to attach. I attempted the ATTACH without a log file option and got this error
The database 'mydb' cannot be opened because it is version 852. This server supports version 706 and earlier. A downgrade path is not supported.
The error message details are obvious i.e attempt to attach a database with a version level higher than the current version of the current SQL Server. The SQL error message says the current server is version 706 and attempting to connect a database of version 852.
Answer:These numbers represent the internal database version of the SQL Server. Each SQL Server version a unique internal database version number.
In this case - version 706 = SQL Server 2012 and version 852 = SQL Server version.
How do you recover the database objects in this situation ? There are three options in How To restore to lower SQL Server version
Do you have any other tips on how to restore a database to a lower version? Leave your comments below
