Since we are discontinuing our z/OS based TSM server, I need to move
everything off.  I am doing this via "EXPORT NODE TO SERVER".

I would like to take this opportunity to change the domains for some of
these nodes.

What are the implication/problems/requirements/gotchas in doing this ?

IIRC, there is a requirement for the domain to have a similarly named
Management Class ?  What about the Policy Set(s) ?
