Sonarqube is in mainteance

I am currently using Sonarqube developer Version 8.0 and working on upgrade through docker to developer version 8.2, when i tried to upgrade this to our non -prod sonar server i am running into an issue with sonarqube been in maintenance.
any sugestions that i could use to get sonar out of maintenance to continue my upgrade

Hi,

Welcome to the community!

You’re currently between steps 5 and 6 of the upgrade guide. Navigate to http://yourSonarQubeServerURL/setup and push the button. That will kick off SonarQube’s migration of it’s own DB schema and soon you’ll be up and running again.
