If ...

Organisation 1 install a ZCM with one ZONE, say "Org1-Zone".

Organisation 2 install a ZCM with one ZONE, say "Org2-Zone".

Both organisations are on the same network and have high-speed links between them.

What, if any, are the interoperability issues between the two zones?

Would it be best to avoid multiple zones if at all practical?

(Apologies if this is a loaded question. :-)

Kind Regards,
