Error after upgrade

Bohumil Dach

Good day,

the following error is displayed after ugprade of Confluence:

Pre-upgrade validation failed. Check the Confluence application logs for more details. You'll need to fix these problems and restart Confluence before you can upgrade. Upgrade error message: Cannot update schema

You should do what it says and check what the application logs say to confirm exactly what went wrong.  Start with <confluence home>/log/atlassian-confluence.log

"Cannot update schema" though strongly suggests a problem with the database.  The application log will tell you the details of that, we can't tell you a lot more without the specfics from the log.  It might just be that there's a dodgy character in the data somewhere, but it's more likely to be a mis-configured database, and there's a chance that it might even be damaged.
