Hello everyone:
We are upgrading from SonarQube 8.9.10 LTS to 9.9.0 LTS.
Since Oracle 12C is not supported by the new version, we have to upgrade the DDBB as well; but we want to keep all projects related previous information.
Is there any changes in the data model for this new version, or can we just copy the database as it is?
Thanks in advance.
Hi,
Welcome to the community!

There are usually changes to the SonarQube schema from version to version, and when you’re going from one LTS to the next, you’re pretty much guaranteed to get changes.
That said, SonarQube takes care of all of that for you. So what you should do is move the data, as-is, to your upgraded DB engine. Then perform the SonarQube upgrade. And as a normal part of that, SonarQube will handle its schema changes.
HTH,
