I just uninstalled SQL Server reporting services native and installed back again from same media which we used 3 years ago. This version is free one (development use only). I configured the report server but am now getting following message.
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 '163'. The expected version is '162'. (rsInvalidReportServerDatabase)
Here is the current version of SQL Server info.
Microsoft SQL Server 2012 (SP3-GDR) (KB3194721) - 11.0.6248.0 (X64)
Copyright (c) Microsoft Corporation
Developer Edition (64-bit) on Windows NT 6.3 <X64> (Build 9600: ) (Hypervisor)
Please help how to resolve this.
