Upgrade Connect iT #

Upgrading Connect iT is done in the following steps.

1. Upgrade Connect iT CLI - To upgrade to a new version of Connect iT Core, the CLI tool corresponding to that version is required.
2. Upgrade Connect iT Core - This will upgrade the web interface, APIs, databases etc. During the upgrade the web interface will be temporarily inaccessible but no video streams will be affected.
3. Upgrade appliances - This will upgrade the software of the appliances routing video traffic. To upgrade an appliance it needs to be restarted. While restarting, the video traffic routed by that appliance will be disrupted.

Version steps #

It’s only supported to upgrade in steps of one minor or major version at a time.

Examples:

• Supported: R3.18.x → R3.19.x
• Supported: R3.19.x → R4.0.x
• NOT supported: R3.18.x → R3.20.x

Core and appliance version compatibility #

Because the appliances will continue running the same software until they are restarted, running one (and no more than one) version older software on an appliance than the core version is supported. Although it’s supported, it’s recommended to upgrade the appliances as soon as possible.

Example:

• Supported: Core version R3.19.0. Appliance software version R3.18.0.
• NOT supported: Core version R3.20.0. Appliance software version R3.18.0.

1. Upgrade Connect iT CLI #

To upgrade to a new version of Connect iT Core, the CLI tool corresponding to that version is required.

Download it by executing the following commands on the machine running Connect iT Core:

curl --output connectit https://docs.cnctit.io/releases/connectit-R3.20.3
chmod +x connectit

2. Upgrade Connect iT Core #

While upgrading Connect iT Core, the web interface will be temporarily inaccessible but video streams will not be affected.

To upgrade, execute the following command:

./connectit upgrade core

3. Upgrade appliances #

After Connect it Core has been upgraded, all the appliances (video, thumb, Edge Connect etc) connected to the core are ready to be upgraded. The appliances will download the new software from the core upon restart.

While restarting, the video traffic routed by that appliance will be disrupted.

To restart appliances, navigate to Settings → Appliances. The status of the appliances will be yellow which indicate that the software needs to be upgraded. Hovering the status icon will show more details.

Select all appliances you wish to restart by checking their checkboxes and press the Restart button. The appliances will restart and download the new software. Their status will change to green within a couple of seconds.
