Appendix B. RHEL 8 repositories
If your system is registered to the Red Hat Content Delivery Network (CDN) using the Red Hat Subscription Manager (RHSM), RHEL 8 repositories are automatically enabled during the in-place upgrade. However, on systems registered to Red Hat Satellite using RHSM, you must manually enable and synchronize both RHEL 7 and RHEL 8 repositories before running the pre-upgrade report.
Make sure to enable the RHEL 8.10 version of each repository. If you have enabled only the RHEL 8 version of the repositories, the in-place upgrade is inhibited.
			If you plan to use Red Hat Satellite during the upgrade, you must enable and synchronize at least the following RHEL 8 repositories before the upgrade using either the Satellite web UI or the hammer repository-set enable and hammer product synchronize commands:
