There are other factors outside of the domain migration to take into consideration as well.  If I rebuild the domain I have to physically go there because to remotely disjoin/rejoin the windows stations, although it can be done, it would be better to be onsite if issues arise.  Next, they have a windows server running some complicated software that is joined to this domain so not keen on disjoining/rejoining that server as I don't know what havoc it would create with some very touchy apps.

I have a post into the zentyal forums to find out if there is a clean migration path to their 6.x version.. so far nobody has responded.  I will give it a while and see if someone answers.  I don't know what Samba version their 6.x product uses but it is very likely higher than 4.5.  

Doing this remotely in off-hours is appealing because I can do it from my home so I can afford to spend some extra "free" time as long as I am careful with VMWare snapshots so I can undo disaster if it occurs :) 

Andrew, what did you mean "as flat as possible"?  I have very little as far as objects in the AD database.. mainly users and if DNS is integrated, DNS entries.  Also not a lot of structure as far as OUs and whatnot.
