Parallel scans with multiple versions of sonar in Jenkins

We are trying to run Sonar 7 and Sonar 9 scans in parallel on Jenkins
Once we are comfortable with Sonar 9 we will turn off Sonar 7.
We are getting the error message
Another sonarqube analysis is already in progress for this project
Is there any way to get around this?

Hey there.

You cannot run two SonarQube analyses of the same project on the same build server at once (even if different SonarQube servers are targeted).

We would recommend doing a round of testing and then upgrading rather than turning one server off and another one on.
