Hi, I would like to know what are the possible issues to encounter when I'm migrating from CentOS 7 to Rocky Linux for iRedmail?

I'm using iRedMail version 1.6.3 due to personal issue with CentOS Stream as I don't like it before but now I left my mail server to old CentOS 7 and that would not be good for security if I don't get security patches support.

Hopefully you can help me to shed some light regarding my concern.

Thanks,

Sean Kevins
