I upgraded SonarQube from version 7.6 to version 9.9.8.
I don’t see the plugins that were installed by default.

Do I need to find and install another plugin or is this just an addition to the default functionality?

Hello @yoonbeen

9.9.8 is already outdated, you should update to 2025 LTA or the latest 2025 build.

The scanners from SonarSource are bunded already for several years with the SonarQube Server, thus you don’t have the possibility to update them separately. Since then they are also not shown in the plugin list, only 3rd party plugins are still there. I think, this started with the 9.x series, which would match your observation. Therefore, it should work even without the plugins.
Some plugins are also replaced by other possibilities, e.g. LDAP is now integrated in the Administration tab of the UI.

Since then you have to opt-in that SQ is not responsible and manually install them in the commercial editions.
