Correct; the "promote CA to renewal master" means promoting an
existing CA replica to be the default replica for certificate
renewal and CRL generation.

Have you kept any of the *replica files* with with the replicas were
created.  The replica file is what is produced by the
`ipa-replica-prepare' command, and is supplied to
`ipa-replica-install' to actually install the replica.  From any one
of these files you can extract the CA signing certificate and run
`ipa-ca-install' on one of the replicas to reinstate the CA.

I have never attempted this but some of the gotchas might be:

- some manual updates in IPA directory might be necessary to "trick"
  it into believe it is a hitherto CA-less deployment

- some config changes may be needed to ensure the new CA instance
  issues certificates starting from an appropriate serial number
  (how many certs were previously issued by the now-lost CA?)

If you can confirm that you do have a replica file I will spend the
time to work out exactly what you need to do.

Cheers,
Fraser
