Current setup
ZEN for Desktops 4.01
W2K workstations
Netware 6.5

I will soon be updating all workstations to XP. So my concernes are:

1. Will I have any issues with ZEN 4.01 and XP?
2. Should I upgrade to ZEN 6.5? if so what are the bennefits?
3. If I upgrade to ZEN 6.5 what effect will it have on the w2k PCs?
4. Will I have to install or change anything on the W2K PCs if I upgrade ZEN?

Thank you
