I'm migrating from one CentOS server to another CentOS server. The plesk panel has been in use for years and even though both servers been upgraded to the latest stable version of plesk, I still get warnings about various Apache modules that are missing. From numerous posts, I can see that they have been removed for security. The question I have not been able to answer is if the "old" server with the current version of plesk is still using them so that it will cause a problem if I migrate without having them installed or if it will not cause a problem because the latest version of plesk doesn't use them anymore. Can anyone shed some light on this?
