  Migrating users (and groups, computers, policies, etc.) from an existing Samba Active Directory (AD DC) to a new Samba AD DC server depends on whether you want to : 1.  Add a new Samba AD server and join it to the same domain  (recommended, keeps all users and objects intact). 2.  Do a manual migration  (export/import LDAP + sysvol, useful if you cannot connect the servers).

  Warning !!! NEVER restore a snapshot. It would break the Samba replication system. Please use the following documentation instead.

  In this documentation, it is assumed: That the main domain controller is called srvads1. That the secondary domain controller is called srvads2. That the domain is called mydomain.lan.

Configuring the DNS name 1. Modify the file /etc/hostname and fill in the FQDN name of the server srvads.mydomain.lan
