Your sticking on the same box and operating system right? (you make no mention of os/box change)
Then all you have to do is BACKUP your /opt/zimbra (tar, zip, copy -idea is to keep all permissions intact-though there is a script to reset permissions if you don't)
Also backup other folders if their not located in that directory; you would know if you've moved them-by default everything runs out of /opt/zimbra.
Then download the 4.5.5 package and as root run ./install-sh
