Here is my situation:

I am running GW 7.03 on a Netware server in a configuration that was
designed 12+ years ago. I want to take this opportunity to develop a new GW
system to have everything properly laid out.

My questions are:

1) Since both GW 7 and 8 systems will be running concurrently until we can
migrate all the users over, can their be 2 GW systems in 1 tree?

2) Our master replica will remain on a NetWare server. If we are only going
to be running the agents (MTA, PO, GWIA...etc) on windows machines, do you
need to install edirectory on those Windows machines as well?
