Not as far as I know, the problem is that samba-tool only knows about
five of the FSMO roles, it knows nothing about the 'ForestDnsZones' &
'DomainDnsZones' FSMO roles, so this means you have to sieze them
manually. Though having said that, I suppose this could be classed as a bug.

Well possibly, so you would have to back everything up and do this when
every other machine was turned off

Very true :-)

I think that in the short term, that is all you can do.
