I do not know what REHEL_RepoID1 and ID2 are supposed to be. I do not have any
Red Hat repos
in my /etc/yum.repos.d, I only have CentOS, epel, etc.
Dead end?
Let's try to use the subscription manager...

[02/04/2021 09:56:06] CRITICAL - The
/usr/share/convert2rhel/subscription-manager directory does not exist or is
empty. Using the subscription-manager is not documented yet. Please use the

Dead end?
In the comments section of
https://urldefense.proofpoint.com/v2/url?u=https-3A__access.redhat.com_articles_2360841&d=DwIBAg&c=gRgGjJ3BkIsb5y6s49QqsA&r=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A&m=iel0E8JL_svyu_6W2ZUso-H4dxqnH78q5ZLs2Y3GXAU&s=juJeIzssALq8uliLKAAoGsvuo4IptowyO_g8EO7iuq4&e=
there is some information
on what to do next, with dates 1-3 Feb 2021 (i.e. fresh just now) and promises
from a Red Hat person
about "We are working on changes that will not require you to pre-download any
package except convert2rhel."
So dead end for now, until Red Hat update the instructions.
To be continued...?
