Upgrading zimbra 6.0.16 to later version
I am still on my baby steps with zimbra's in's & outs.
I need to upgrade a zimbra stand alone server from (Release 6.0.16_GA_2998.UBUNTU8_64 UBUNTU8_64 FOSS edition) to later edition. I read about upgrades on the net with unclear directions. then thought of contacting the gurus.
I am aware that this server have missed several upgrades (OS and zimbra application) already. I can highly appreciate your input in this regards, as I am scared to break a live system.
