Switch back to community edition from developer edition

SonarQube Server / Community Build
1

Hi All,

After using Sonarqube community edition for several years, I tried the developer edition with a trial version.
I know want to switch back to community edition but I’m blocked.
I deployed with Helm the 2025.2.0-developer version (Sonarsource Chart Repository). When I switch to the default community version of this chart (25.1.0.102122), i get this error :

java.lang.IllegalStateException: cannot downgrade a node from version [8.16.3] to version [8.16.1]"`

I tried to deploy the versions 25.2.0.102705 and 25.3.0.104237 but i have the following error :

Caused by: org.sonar.api.utils.MessageException: Database was upgraded to a more recent version of SonarQube. A backup must probably be restored or the DB settings are incorrect.

Is there a way to return to the community version without restoring the datas from two weeks ago ?
If the structure is the same between developer and community version, can I tweak the database to return to community ?

Thanks for your your insights.
Nicolas

Hey Nicolas,

You’ll have to wait for Community Build 25.4 to be able to switch back. You cannot downgrade to any version of SonarQube Community Build that was released prior to the version of SonarQube Server you upgraded to.

Community Build 25.4 is due next week.
