Upgrade the system software (page 1 of 2)
Upgrading from TC to CE software
CE software is the evolution of TC software. We recommend 
that you upgrade to TC7.3.6 or later before you upgrade to CE 
software.
It is important that you read about upgrade requirements and 
functionality changes before you upgrade to CE software. 
Also check that your environment supports the changes. We 
recommend reading the Software Release Notes carefully. 
If you don’t take into account these considerations, upgrading to 
CE can leave you with a non-functioning deployment that requires 
you to downgrade. 
Upgrading from CE8 to CE9
The MultiStream feature with Cisco TelePresence Server is 
deprecated in CE9. 
Also, some features that were available from the Touch controller 
in CE8, are not available in the first CE9 releases. Read the 
Software Release Notes for details before you upgrade.

CE software does not support the 
following features and products:
 - TRC5 remote control
