Section Number and Name:
14.1. Restoring from a Full Backup

Describe the issue:
The 1st prerequisite for restoring a satellite from backup is:

Ensure that you are restoring to the correct instance. The Red Hat
Satellite instance must have the same host name, configuration, and
be the same minor version (X.Y) as the original system.

What is meant by "configuration" is unclear.

Suggestions for improvement:

Ensure that you are restoring to the correct instance. The Red Hat
Satellite instance must be similarly sized (number of processors,
memory & storage), have the same host name, and be the same
Satellite software minor version (6.y) as the original system.

Additional information:
I thought it might mean that if the source satellite was setup as a DHCP server, the destination needed setup as one, too. Yet I did a restore of such a satellite to a destination that was not setup that way and it appears to have come out of the restoration as a DHCP server.

Upon asking about this in the satellite-tech-list mailing list, I got this response:
