Hey Guys,

My internal mail server is installed on a Dell box with centOS 5.
i have the following version of Zimbra installed:

Release 5.0.9_GA_2533.RHEL5_64_20080815094512 CentOS5_64 FOSS edition

----

i'd like to get my current version uptodate and or upgrade to version 6.
May i ask for someone to point me in the right direction as im not quite sure if we have the open source or network edition installed and also moving forward the best way to update/upgrade...

any help/guidance would be uber appreciated
