When you upgrade Microsoft SQL Server Reporting Services instance from Microsoft SQL Server 2012 Service Pack 2 (SP2) Cumulative Update 12 (CU12) or later versions to SQL Server 2012 Service Pack 3 (SP3) or SQL Server 2014, you may receive an error message that resembles the following:
The version of the report server database is either in a format that is not valid, or it cannot be read. The found version is ‘164’. The expected version is ‘162’. (rsInvalidReportServerDatabase).
This issue occurs because of a change is made in SQL Server 2012 SP2 CU12 that results in a new ReportServer database version. Because this fix is made after the SQL Server 2014 release, if your SQL Server 2012 SP2 server is on CU12 or a later version, it will have a higher database version than what SQL Server 2014 RTM expects.
Update informationThis issue was fixed in the following cumulative updates for SQL Server:
- Cumulative Update 5 for SQL Server 2012 SP3
- Cumulative Update 8 for SQL Server 2014 SP1
- Cumulative Update 1 for SQL Server 2014 SP2
Or, you can upgrade to any build of SQL Server Reporting Services 2016. After you apply the fix, the Reporting Services instance can recognize the new database version correctly.
