Sorry, but this is confusing? Why don't you want to loose POSIX ACLs 
when the new filesystem doesn't support them anyway?

I would basically rsync, preserving xattrs, and set POSIX filesystem 
permissions to 0777/0666. vfs_acl_xattr will be serving NT ACLs from the 
migrated xattrs, ignoring filesystem permissions given that 
"acl_xattr:ignore system acls = yes" is set.
