Upgrading the Cisco TelePresence Server on Virtual Machine
Note: This section is not applicable if you are upgrading a hardware platform TelePresence Server.
The upgrade process for a Cisco TelePresence Server on Virtual Machine is very similar to that of the
hardware platforms, although there are some differences. You must comply with all the Prerequisites and
software dependencies [p.30], unless an item is explicitly excluded from the Virtual Machine platform.
The main differences in the Virtual Machine upgrade are as follows:
n The upgrade file for Cisco TelePresence Server on Virtual Machine has a .tgz file extension.
n After doing the software upgrade via the TelePresence Server web interface, you need to adjust the number
of physical cores dedicated to the virtual machine and may need to adjust the RAM. These changes require
that you power off the VM.
