Upgrade UCT-V manually on Virtual Machine

To upgrade UCT-V manually on a virtual machine, delete the existing UCT-V and install the new version of UCT-V.

Note:  Before deleting the UCT-V, take a backup copy of the /etc/uctv/uctv.conf configuration file. This step avoids reconfiguring the source and destination interfaces.

1. Uninstall the existing UCT-V. Refer to the Uninstall UCT-V section in the respective GigaVUE Cloud Suite Deployment Guide.
2. Install the latest version of the new UCT-V. Refer to the Linux UCT-V Installation and the Windows UCT-V Installation topics in the respective GigaVUE Cloud Suite Deployment Guides.
3. Restart the UCT-V service.
   • Linux platform:

     $ sudo service uctv restart

   • Windows platform: Restart from the Task Manager.
     

Upgrade UCT-V through GigaVUE‑FM

Upgrading UCT-V manually involves a series of steps to uninstall, install, and restart the service again. This method can be complicated when you need to upgrade UCT-Vs for a large number of VMs.

However, you can upgrade UCT-V in the workload VM without any hands-on involvement through GigaVUE‑FM. Refer to the sections below for more details and step-by-step process:

1. Upload the UCT-V Images

2. Upgrade the UCT-V

Rules and Notes:

■

Currently, upgrades are only allowed to versions 6.9.00 or later. Ensure that the UCT-V Controller version is compatible with the version to which you are upgrading.

■

You should have Infrastructure Management permission to upgrade the UCT-Vs.

■

Currently, you can upgrade the UCT-Vs to n+2 versions and any number of patch releases through GigaVUE‑FM.

■

Before you proceed with the upgrade, ensure that the UCT-Vs are in a healthy state.

■

A UCT-V can only be associated with one active job at a time. If the selected UCT-V is part of another job, you cannot trigger the immediate job using the same UCT-V.

■

You must upload a compatible image type to upgrade the UCT-V; otherwise, the UCT-V will be rejected for the upgrade job.

■

Upgrade through GigaVUE‑FM is not applicable for OVS agents. For OVS tapping, you should upgrade the UCT-Vs manually.
