Need to upgrade to 8.9 lts from 8.5.1

I am currently on 8.5.1-developer docker tag. Would like to upgrade to 8.9 or 9.*. What steps should be taken?

I am currently running sonar on kubernetes.

Hi @Vorteg_Anum ,

you should follow this path : 8.5 → 8.9 LTS version (–> 9.1 current latest version - last step isn’t mandatory).
Upgrade process is described here: Upgrade Guide | SonarQube Docs
And you can read the Release Notes before upgrading, to help you detect any potential issue for your CICD integration: Release Upgrade Notes | SonarQube Docs
