based on the fact that CentOS7 is going to be maintained (and not closed in 
December 2021) I would not force any moving to OLVM 4.3.10 (when 
available)/OL7, unless you are interested on support.
Our plan, for sure, is to get OLVM 4.4 GA in the 2021 and, so, at that point 
you could evaluate the moving.

yep, the script is on GitHub (if someone is interested to also leave feedback): 
https://github.com/oracle/centos2ol <https://github.com/oracle/centos2ol> 
for oVirt we’ve dedicated channels for OL7, you’re right.

This one could be for sure a valid plan.

Right.
