We did that recently by building a new empty domain. Then we exported users
data in LDIF to get everything but passwords.
We don't bother with what follows because we were still in test and had
only few users/computers to re-join and because user's passwords can be
re-injected into AD from another LDAP tree.
Andrew wrote a patch to add a command "samba-tool domain clone" but I have
no idea if it is already included in 4.4.5 nor how it really works, I
haven't tested it.
Without changing domain' SID users will be considered as identical by
Windows clients (they rely on SID) and so you would avoid the need of
For computer accounts re-using SID could not be sufficient. Even if
"samba-tool domain clone" extracts passwords in a form you can re-use them,
it is still possible that Windows client' system is glue to old domain
name, it is possible that you really need to extract them from old domain
to join them the new one.
For GPO they are hosted into LDAP tree and into SysVol share. For file in
the share, no issue. For LDAP data you would have to extract the DB in LDIF
to inject them. And that's a tricky point into which I didn't yet dug
