Upgrading to XC2.3.1
Upgrade requirements
Note:
n Releases XC2.3 or later include a patch for CVE-2014-0160.
n After upgrading to XC2.3 or later we strongly recommend that you generate and install new server
certificates on your TelePresence Conductor systems.
The upgrade requires you to have:
n a valid Release key, if you are upgrading the major release of the TelePresence Conductor (for example
from XC1.2 to XC2.3.1).
A release key is not required for:
l dot releases (for example XC2.0 to XC2.3.1)
l systems that are running without a release key and with limited capacity (as TelePresence Conductor
Essentials)
Note: If you do not supply a valid release key when upgrading the major release, your system will run as
TelePresence ConductorEssentials with limited capacity.
n a software image file for the component you want to upgrade, stored in a location that is locally accessible
from your client computer.
To avoid any performance degradation we recommend that you upgrade the TelePresence Conductor while
the system is inactive.
