This sounds abit like the switch from samba3 to samba4 ad back then. :-)
I guess chances are good the domain name is hidden in some binary blobs 
inside the ldap tree. So using ldbedit would be difficult and not just 
somethng like an slapcat and sed thing. I'm curious if that method from 
rowlands link works with samba, so if i find some spare time i'll give 
it an try.
Meanwhile i'll leave things at .local after reading all the remarks and 
recommendations here.
Might be helpfull to others if some of the advices about avahi and 
nsswitch.conf find there way into the wiki, for people like me already 
using .local and considering an migration.
