I’m trying to upgrade sonarqube version 7.9 to 8.6 and migrate the existing database data (postgres) from the old version onto the new. I tried to follow some online documentation found on the web on how to do this but it doesn’t seem to work. Sonarqube web app says SonarQube Under Maintenance after a successful database data import. Create and restore PostgreSQL backups
On inspection of the database schema backup sql file used between sonarqube versions it seems the schema between them are different and as well as the fields within the table are also slightly different, making database backup and recovery between the sonarqube versions incompatible.
Does SonarQube have an export function of some kind that would allow me to backup existing database data that can later be imported and use on a newer version?
