About to switch to Developer Edition

I am planing to use the Developer Edition so I can leverage PR analysis. I am presently running SonarQube lts which is 7.9 in a Docker swarm with a postgresql backend.

For developer edition I only see :developer-beta tags in Docker, but not a release version. I am thinking I just need to upgrade my SonarQube instance to developer-beta and I am guessing putting in the license key when I complete the order. Is there anything I may be missing before I start the order process?
