You can't. The whole point of replica installation by promotion is to 
eliminate the need to lug around files to set up new replicas.

In domain level 1 the ipa-replica-prepare command is disabled and 
running it raises an error (See test case 2 in 
http://www.freeipa.org/page/V4/Replica_Promotion/Test_plan). Also there 
is no MASTER domain level, the domain level is uniform across the whole 
topology

Topology segments describe replication agreements between *two* 
endpoints (think about them as graph edges connecting two nodes). So you 
set up a segment between replica1 and replica2. To connect third replica 
to the topology, you have to create new segment connecting either 
replica1 and replica3, or replica2 and replica3.

I'm not quite sure about point 3 either. I guess that you have to 
reenroll the replica after restore, but maybe someone more knowledgeable 
about the feature will chime in.
