eGroupware upgrade, installation of extra software possible?

[bbking]

Hi,

I am kind of working on the eGW / Thunderbird / Blackberry sync (see http://forum.ebox-platform.com/index.php?topic=3618.msg15620#msg15620) and I got a message in the eGW forum that I need at least eGW version 1.6.003 (EBox runs 1.6.002).
Can I upgrade somehow without breaking the EBox settings? If yes, how can I do this?

I'd also like to install additional software, e.g. drivers for my usb webcam, a media streaming server, etc. - can I do this without breaking something?

Thanks a lot in advance!
