[Samba] Migration strategy

[Anders Östling]

I am in the process of setting up a new AD based on only Samba
servers. The current domain has a number of Samba file servers and 2
windows dc's that are going to be retired.

The accounts and groups in the new AD will have the same names (but
new SID's) and be created directly in the new domain. What I need to
figure out is how I can migrate data on the file servers to the new
servers without bringing with me the old ACL's. All directories and
files are owned by specific groups in the current domain.  Therefore I
need to find a way to copy (rsync,robocopy, tar, ...) the directory
trees to the new servers.

What would be the correct way to do this? I.e end up with a directory
tree where the files have "NEW-AD\Owner-group" instead of
"S-RANDOM-SID" as owner.
