Rajesh,
If I understand your question...
You currently have a DMM 5.2 appliance. Most likely
for Digital Signs or Cast. Now, you are purchasing a
Show and Share Appliance with 200 authors and you
want to integrate the two appliances into a DMS Suite.
This should not be an issue. You will need to purchase the
appliance and the appropriate licenses needed for Show and
Share.
If you have any questions relating the part numbers or what
exactly to order, please contact your Cisco Partner or Local
Cisco Sales Team.
Thanks!
T.
