I would put it another way. You want to choose a realm name,
and never ever change it afterwards (it is so with all names which
are actively used).

So you would begin with allocating a DNS SRV record for your realm.
Alternatively (SRV records may be unavailable at your place)
allocate a DNS A or CNAME record to point to your future server.

You _can_ replace that operation by a line in the "realms" file
on a client, but remember that it is not supposed to be used in production,
it is just a debug/workaround mechanism.
Realm names do not belong to a client setup.
All clients are supposed to have the same idea about realm names,
without any extra administration per client.

You can access the same Coda data via several paths like

but those are useful for testing, not meant to be used otherwise.

You should use always
as it is the only relevant one - and it is not going to change.

Traditionally it was not possible - recreation was the only option.
Nowadays you can try to extend volume replication groups.
