Storage units need to be recreated after Master server changed?

I need to move my environment to a new clustered Master server. WWN  for the tape drives and robots will stay the same.  I have two questions:

1.Do I need to recreate storage units for the Media servers after that? If I change the bp.conf and restart the NBU processes, these will autmatically put my storage units controlled by new Master server snad Media server?

2. If the robot number changed -- previous TLD 0 became TLD1, previour TLD1 became TLD 0. Does this matter?
