We are getting the below error in report server DB.
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 '163'. (rsInvalidReportServerDatabase) Get Online Help
How we fixed this issue:
1. update ServerUpgradeHistory set ServerVersion=163 where UpgradeID=3
2. select * from ReportServer.dbo.ServerUpgradeHistory with (nolock);
3. Restart the reporting services.
@hemanthsmg01 (yes I know this was a year+ ago)
Essentially you forced your Reporting Services DB to "find" the new version as the old version? Is that what I'm getting out of this reply?
We're having a similar issue, different versions of course. If we don't need to nuke our report server and start over, we don't want to, but none of use are server admins (just devs) and we're working in a test environment that hasn't had reporting services set up since ~2016
If this is a true fix that worked (long-term) and didn't require any other actions, I might try this first, but if you get this and can comment that'd be great.
