Every server is a master. The only differences may be the services 
running (CA and/or DNS) and only one generates the CRL and manages 
certificate renewal. Otherwise they are all equal masters.

This doesn't show the topology. Were I to guess it looks like:

    001
   /  \
002  003

So you need to run ipa-replica-manage connect vuwunicoipam002 
vuwunicoipam003

Then you should be able to delete 0001. Just be sure at least one of 
those other masters has a CA, if not both of them. You may need 
ipa-csreplica-manage connect to connect that topology.

Also be aware of the DNA config. A master doesn't automatically get one. 
It only gets it when it creates an entry that needs a range.
