Going to be migrating a nw6 server to new hardware. This server
basically is only my master time server and is the master of all my
edir replicas.

What would be the best / easiest way to migrate this? Should I go thru
the migration, or should I make a different server the master of my
replicas, remove the existing server from the tree, then put the new
one in the tree & make it the master?

Looking for the easiest, best, safest way.
