Dear all,

Little question here.

I've installed yesterday the open source version... Very nice to see it is working fine. Now i wanted to try the exchange feature for on my mobile HTC. For that I need to install the network edition. Can I use the Trial version without re-installing everything and upgrade the open source.
And if afterwards, I want to go back to the open source (it's a test server) Can we do that without issues and loosing mails?
