Make sure to tell us:

• What version are you upgrading from?8.9.6
• System information (Operating system, Java version, Database provider/version) :rhel8,java17,postgres 11.16 AWS rds
• What’s the issue you’re facing? Difference is scan results

I could see the difference in # of bugs and Code Smells on the same code/repo after the upgrade.

scan before upgrade:

scan after upgrade:

is this expected!
(this is seen for other fields as well on different projects.)

Hi Dev,

You can expect some changes in terms of the issues that are reported by SonarQube 9.9 LTS. The new LTS adds many new rules and brings significant improvements to the existing ones.
I invite you to check the issues that were recently opened and closed to understand the reason for these changes.
