Okay to delete these directories?

/opt/zimbra/redolog-pre-4.0
/opt/zimbra/redolog/4.5.3_GA-1.12
/opt/zimbra/openldap-data.prev
/opt/zimbra/openldap-data.prev.10730
/opt/zimbra/jdk1.5.0_06
/opt/zimbra/amavisd-new-2.3.3
/opt/zimbra/amavisd-new-2.4.1
/opt/zimbra/backup-pre-4.0
/opt/zimbra/clamav-0.88
/opt/zimbra/clamav-0.88.4
/opt/zimbra/clamav-0.88.5

They are taking up a few GB in total on disk (let alone in backups) and if I don't need them anymore then I'd like to remove them.

I suspect I don't need them anymore, but I'm just making sure.

FYI: We are currently running 4.5.4 with the tomcat fix.

Yes.
But just to be sure, i'd move them to a place out of /opt/zimbra first to make sure everything works, before blasting them away
