Hi, I've a migrated samba-ad on my test-machine. Is it possible to transfer the samba directory (stored under /var/lib/samba) to another machine/my productive system? I would to these steps: - install samba and dependencies on new host - transfer my /var/lib/samba, /etc/krb5.conf and /etc/samba - start samba service Do I have other things to consider?

However if you must, the above is OK if you keep the same 'netbios name' and don't run both at the same time. Better still is using Samba 4.9 to backup the old domain and restore it again.

AFAIK, Samba 4.9 isn't stable release yet (so I won't risk placing it into use outside a sandbox). If there's convenient and portable way of dumping/loading Samba 4.7+ data, I would also appreciate mentioning it, immensely. Thanks. Sincerely, Konstantin
