SonarQube Enterprise Edition Upgrade Best Practies

We are planning to upgrade to 9.9 LTS. I wanted to know about the things to note or best practices to follow during the upgrade. This is the first time we are performing the upgrade.

Details as:
Current SonarQube Version: 9.6
Helm Chart: 4.0.2

Target SonarQube Version: 9.9
Target Helm Chart: 8.0.0

Also, we plan to jump from helm chart v4.0.2 to v7.0.0 before making the final jump to v8.0.0 to minimize backward compatibility issues.
Make sure to tell us:

Hi,

You’ll want to check the release upgrade notes for all the intervening versions, and of course follow the upgrade guide.

 
HTH,
Ann
