No, it's not that complicated. The simplest way would be to just use
db2ldif to dump your replica database, then use ldif2db to import it
into the master. Then reinit your replica from the master.
Phew!

I'm not sure what you mean.
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
