Generally, I would swap them over at some point (probably best to do it 
now while the other server doesn't exist) , just stop both, change the 
slave/master setting, and restart.

The only difference is the master runs the mailing lists, the slave 
doesn't (this avoids some nasty complexity)

So really it doesn't actually matter when both are running you can leave 
it if you wish.  But when only one is running for an extended period you 
do want it to be the 'master'...
