I want to roll back ondemand from 3.0 to 2.0, what is the appropriate way to do that?

My instance use redhat8.5, after I upgraded from version 2 to 3, I realize that I need to keep one test instance at version 2.0.
Now I want to roll back tow version 2.0,
I want to get some suggestions on what is the correct or appropriate way to do that.
Thank you very much.

Hi and welcome!

You should be able to just remove all ondemand related RPMs, and reset the ruby version back to 2.7.

Should just be something like this, then follow the instruction back to install 2.0.

dnf remove ondemand-*
dne remove ruby
dnf module reset ruby
dnf module enable ruby:2.7
