I understand that and that's why we worked on the upgrade feature so 
that user can upgrade to
a newer version operating system.

Given the Fedora Atomic to Fedora CoreOS is a big jump, I don't know if

Again, we're working hard on this but we don't have a perfect solution 
due to the limited resources.
