As the summary specifies, it is unknown if an update for the Satellite to the latest z-stream is necessary or not to avoid any possible untested scenarios. I can only assume that testing for leapp upgrades for Satellite servers are done on the latest z-stream for RHEL 8 going to the latest z-stream of RHEL 9. However, the documentation does not state that an update to the latest z-stream of Satellite 6.16 on RHEL 8 is necessary before performing the leapp upgrade to 6.16 on RHEL 9.

Should the required steps for a leapp upgrade be prepended with a Satellite update before attempting to leapp upgrade to the latest Satellite version on RHEL 9?
