In addition to Yaniv's explanation below, can you explain why it was
bad? That is, what software/process was broken by it? Please note that
this is the CN of the CA's cert, not of the individual certs its signs
(such as the one for the web server for https) - these have the FQDN
you supplied to engine-setup as their CN.
The 5 random digits are supposed to be OK, and are actually a feature - it
ensures uniqueness if you re-generate (most likely reinstall your Engine),
as otherwise some browsers fail miserably if a CA cert mismatches what they
know.
SAN is being worked on - we are aware of Chrome 58 now requiring it.
I sincerely hope to see it in 4.1.2 (see https://bugzilla.redhat.com/1449084
).
Indeed, and see my comment 5 there for how to add SAN to an existing
setup, _after_ you upgrade to 4.1.2 when it's out.

This depends on several different factors, including the expected cost
of full export/reinstall/import compared to partial solutions. If you
have a small setup that can have downtime, and have enough resources
to prepare a more-or-less complete test environment where you can
verify what you plan to do, then export/reinstall/import (where export
is not really needed these days, the engine can import an existing
storage domain) is the safest option.
