Troubleshooting: Restore error-Unknown Sql Exception (Number=3169), Message=The database was backed up on a server running version XX.XX.XXXX

Question: When I restore a backup file, the system prompts a message as below. Unknown Sql Exception (Number=3169), Message=The database was backed up on a server running version 12.00.2000. That version is incomplete with this server, which is running version 11.00.5388. Either restore the database on a server that supports the backup, or use a backup that is compatible with this server.

Version: 1.8 / 1.9 / 2.0

Possible Reason:

The version of SQL Server (SQL Server 2014) for the account book to be restored is higher/newer than that installed in your existing server (SQL Server 2012).

Solution (1):

The user needs to upgrade SQL Server to the version that compatible with the backup file. In order to know which version is appropriate, you may refer to the following list:

The first digits refer to the version of SQL Server such as:
10.0 for SQL Server 2008
10.5 for SQL Server 2008 R2
11.0 for SQL Server 2012
12.0 for SQL Server 2014
13.0 for SQL Server 2016
14.0 for SQL Server 2017
15.0 for SQL Server 2019
16.0 for SQL Server 2022

Solution (2):

If the user does not wish to upgrade the existing SQL Server version with instance A2006, then they may install the require SQL Server with another instance name.

When restore the account book, remember to use the Restore the data in any PC option. Server name key in (local)\<<New Instance Name>> and always make sure the Test Connection is successful. Then you can continue with restore backup file.
