## Updating a plugin <a href="#upgrading-plugin" id="upgrading-plugin"></a>

See [install-a-plugin](https://docs.sonarsource.com/sonarqube-community-build/server-installation/plugins/install-a-plugin "mention"). For the Community Build, see [marketplace](https://docs.sonarsource.com/sonarqube-community-build/server-update-and-maintenance/update/marketplace "mention").

## Downgrading to SonarQube Community Build

Ensure the target SonarQube Community Build version was released after the source SonarQube Server version. See [Releases - Sonar Community](https://community.sonarsource.com/c/sq/releases/24) for release dates of SonarQube Community Build and SonarQube Server. In most cases, migrating to the latest version of the target product will suffice.

However, if you are using the latest version of SonarQube Server, you may need to wait for the next version of SonarQube Community Build accordingly, typically available within a month.

Once the target version is confirmed, proceed with the standard update procedure.

To update your SonarQube Community Build to SonarQube Server, see [Upgrading from SonarQube Community Build](https://docs.sonarsource.com/sonarqube-server/server-update-and-maintenance/update/updating-from-sonarqube-community-build).
