I'm currently running ZFD 3.2 SP3 on NetWare 5.1 SP7. One server hosts all
ZFD services. We specifically use inventory and remote control. Users
drives are mapped through a login script. This is for corporate campus only
with approx. 600 PCs. Workstations are a mix of 98SE, NT4 and XP.

I'm shortly going to upgrade the server to NetWare 6.5 SP2. I would also
like to upgrade ZFD 6.5 but have the following concerns:

1. Do I need Middle Tier services? If so, can these run on the same server
I use for import and database?
2. Will I have to delete and re-create all my associated objects for ZFD?
3. From what I'm reading, the import process has changed. Am I going to
have to touch every client?
4. NAL is currently run from the login script. Will that change also?

Any insightful info appreciated.
