Got the following error while trying to upgrade Teamcity 4.5.4 to 5.1.2:
ERROR - jetbrains.buildServer.SERVER - Server startup exception: jetbrains.buildServer.rootDispatcher.KnownNonRecoverableStartupError: Database version mismatch:
Database version mismatch: Configuration version is 343 but Database version is 0.
We are using external MySQL database.
I also tried 4.5.6 and 5.0 versions. With 5.0 I got the same error, but 4.5.6 worked just fine.
It seems new TeamCity can't determine which version of database I've got.
If it matters, this database initially was created on 3.1 version then upgraded to 4.5.4.
