Hi,
A lot changed between 7.9 and 9.9 including some coverage parameters.
You should check all the upgrade notes as well as reading your analysis log.
The analysis / scanner log is what’s output from the analysis command.
This guide will help you find them.
And BTW, 9.9 is no longer the LTA. 2025.1 LTA was released last week. You should finish your migration journey.
