I searched the forums and the Internet to find a answer for my question, but could not find any. I noticed the version of Apache that comes with Zimbra v.4.5.9 is older than the latest stable version. I would like to upgrade to that version, but was wondering what kind of problems I could run into. Can anyone point me in the right direction (articles/topics) or maybe share some knowledge? I really would appreciate that.
Btw: I have some experience in upgrading Apache on itself.
