server renumbering

We managed to kill our Zookeeper cluster by renumbering the servers in 
zookeeper.cfg. Obviously there is some internal  id that is created when 
the nodes are added and changing that break things dramatically. We had:

server.1=hostA.internal

server.2=hostC.internal

server.3=hostB.internal


We renumbered them, causing the problem.


For the future, is there documentation for the best process to replace 
and renumber hosts?
