Phew!

When we installed the first server, we told it there was no existing
directory server instance with which to register. When we created the
RO replica server, we told it to register with the existing instance.
How do we handle that now that the original instance has been destroyed?
What did registering it do? Thanks - John
Ah, ok. I think you need to run the register-ds-admin.pl command after
you restore the data on the master, and tell it you want the master to
be the configuration directory server.
Then you'll have to run setup-ds-admin.pl -u (or possibly
register-ds-admin.pl) on the replica to register it with the
configuration directory server.
