We are currently on SonarQube Version - 6.3.1 and using below plugins :
Are these compatible with SonarQube 8.9.1? Planning to upgrade to 8.9.1
Hello @mtyagadurgam ,
welcome to the community
i would say no as 6.3 is way past eol. i would recommend you to take a look at our version compatibility matrix and our upgrade guide. when you are upgrading from 7.9 to 8.9 you should also take a look at our LTS to LTS upgrade guide.
for individual 3rd party plugin questions you should ask the maintainer of the respected plugin.
hope that helps
