I think you can upgrade directly, but you should test before

Ok, but how to test without crash my current system ?

[dalmate]

You use a machine, then you install 5.0.12 on it. migrate some data to it and try to upgrade --> Test it : data, account, send and receive mail --> if it's ok --> you can try

I successfully update to 5.0.18, but from 5.0.18 to 6.0.1 postfix isn't running and i downgrade my zimbra server.I dont now why postfix not startet

[dalmate]

Can you type this command with zimbra user:
postfix reload (it'll reload postfix for you)

or you can check:
zmcontrol status

and check the log for detail
