This procedure is in fact a bit confusing and we have a bug to clean it up.
https://bugzilla.redhat.com/show_bug.cgi?id=813880

The purpose of this procedure however is simple: to define which of the
CA instances has to be the authoritative source for the CRLs. Only one
CA can be an authoritative source at a time so if you lost a replica
that was responsible for this (and by default this is the first master
you install) you need to go to some other replica that has CA and follow
this procedure to make it be the source for the CRLs.
This is the goal of the "promotion". There is nothing else to it.

HTH.
