I am planning an upgrade from version 4 to version 7 and had a few
questions. I want to migrate the Zen services to a new server but wanted
to know if the Zen 4 and Zen 7 server could co-exist in Edirectory? Will
this confuse the workstations or Console1?

Or should I upgrade the Zen 4 server to Zen 7 then migrate the server to
the new hardware?

Thanks in advance
