[Samba] Migrate and Update (Samba 4.1 ADDC to Samba Latest Version on different Server).

[Juan Ignacio]

Seems like the online backup worked if i backup the original DC "DC1", not
if I put the new one "DC2".

Of course i'm using the command on the new server with 4.16

samba-tool domain backup online --targetdir=/domain/samba/domainBackups
--server=DC1 -UAdministrator  Worked!!

samba-tool domain backup online --targetdir=/domain/samba/domainBackups
--server=DC2 -UAdministrator NOT WORKED

Any suggestions? To check the errors.
