This document describes the upgrade procedure and steps required for Cisco TelePresence Server (TS) upgrade to 4.3(1.13)
There are no specific requirements for this document.
The information in this document is based on these software and hardware versions:
TelePresence Server on Virtual Machine 4.2 and earlier
Due to platform operating system changes introduced in version 4.3 you cannot directly upgrade from OR downgrade to 4.2 and earlier versions from 4.3 and later.
To upgrade 4.3, the Cisco TelePresence Server on Virtual Machine needs to be redeployed using the .ova file. Using the upgrade redeployment tool ensures serial numbers are preserved, and thus all the keys (activation, encryption, screen licenses) are carried across to the new deployment.
Once you have deployed a 4.3 Cisco TelePresence Server on Virtual Machine, you cannot downgrade to 4.2 or earlier. If you have kept the old 4.2 Cisco TelePresence Server on Virtual Machine VM, you can power that on (assuming you power down the 4.3 Cisco TelePresence Server on Virtual Machine VM) at any time and resume using it.
Caution: You will need to get new activation and license keys if you redeploy without using the upgrade redeployment tool.
Task 1. Ensure all prerequisites are met.
Task 2. Download and install the vts-redeploy-n.n.tar.gz package.
Task 3. Prepare configuration and/or batch files as necessary.
Task 4. Run the redeploy_vts command.
Task 5. Verify that your new Cisco TelePresence Server on Virtual Machine(s) are up and running.
