Note2: This installation guide applies to WebRTC gateway installations on VM and standalone PCs since version 1.67.

How to upgrade the WebRTC gateway (available from 1.67.6-121)

The upgrade is performed with the mpupgrade command; Details about all “mp” commands can be found with mphelp.

Step 1

First you must copy the new version into the folder upgrade located under the root directory of the WebRTC gateway.

The files that need to be put into this folder are the iso and the iso.md5 files.

For example, you can use the tool WinSCP:

Step 2

Run the command mpupgrade (optionally you can configure a delay before the upgrade is performed automatically)

In following example I’ve delayed the upgrade by 30 seconds.
Once you have confirmed with ‘YES’ (note: it is case sensitive and must be written in capital letters) the upgrade starts with the defined timer delay (note that with the option --now it can start immediately).

From now everything is automatic, first the server will reboot and start the upgrade (default value in Grub bootloader)

The upgrade is performed

And the server will reboot once and start with the new version

Step 3

Note that the keyboard and ssh configuration are keep BUT the “rainbow” account password is not restored and is again the default one Rainbow123.

You can run the command mpcheck to verify that the configuration has been restored and that the WebRTC gateway is running well and connected to Rainbow cloud.
