This weekend I am migrating all of our servers to new racks servers. I
choose to use this time to essentially rebuild the network of about 70
users. I have setup a new tree and imported the users into it already.

We had been using ZFD 4 and are now going to begin using 6.5. What if
anything should I do to the workstations? Is there a new ZFD agent that
needs to be installed? I saw an earlier post about workstation imports.
Obvuiously, I want to have the 70 desktops imported again but into the new
ZEN system in the new tree. Are there reg keys that I need to remove (ie
HKLM\Software\novell\workstation manager\identification) in order for the
workstation to import itself into the new tree / zen system?

Any guidence would be appreciated.
