as you can see at my other forum posts I'm absolutely fascinated by Zimbra. I currently have installed the last version of Zimbra on a FC3 server.

I am using it for my family on a home network.

The network version will cost 30 dollars per year and account and I will definitly buy it.

No my question: Can I simply upgrade? Or will I have to make a re-install? Will I be able to import the existing data?

Another question: When will the network version be out? I read something of "November", but is there an exact date?
