CBD Upgrade from 2.7.1 on Linux (ubuntu 20.04) to 2.9.1

[AbbyDoc]

Hello,

I have CBD 2.7.1 running on Linux (Ubuntu 20.04) in Azure and would like to upgrade to 2.9.1. I get the following:

Cisco Business Dashboard version 2.9.1 is available for upgrade but is not supported on this operating system version (Ubuntu 20.04.4 LTS (focal fossa)).
Please take a backup of the dashboard using the System > Backup page. Then create a new dashboard install based on the latest version. You may then restore the backup to the new dashboard.
See the Cisco Business Dashboard version 2.9.1 Cisco Business Dashboard - Cisco for details on upgrading.

I follow the instructions in the guide, but it does not work. There are certificate issues, and the devices will not register after restoring backup to a new Azure VM running. (22.04).

Kind regards

Abby

No, it is not running yet, as it did not work the first time I tried, I am going to build a new VM with CBD 2.9.1 following the steps above.

Hello @Mark Fang 

Thank you very much for your support and prompt responses.

I have now managed to migrate CBD 2.7.1 on the VM in Azure to CBD 2.9.1 on a new VM running Ubuntu 22.04 following the confirmed steps you suggested above.
