02. What is the minimum version of CentOS that can be supported?

CentOS 7 is certified and tested for GMiD™Box. So, the latest version 7.6 is the best choice.

We gave up to support CentOS 8.
Our plan is to move from CentOS totally to some other distributions because CentOS won’t be the same anymore. RedHat totally changed the politics of CentOS.

This will happen in the next Next 3-6 months. (Jan/21)

We will be moving to Oracle Linux. And of course, we will keep support for RedHat Enterprise Linux – RHEL
