Hi, We have an upcoming project to migrate Samba first into a new Hardware then the AD migration. Our hardware is old and we need to migrate. Please allow me to explain the current setup - Server : Physical - OS: Ubuntu 14.04 running Samba 4.0.0. Even though it is running Samba 4, we are using configs from Samba3. - Roles: DC, DNS , DHCP and Shares - Database: TDB - DNS: BIND9 - Clients: Mix of Windows 7 and 10 joined to the domain Here is what we are planning, high level Phase1: - Add a new Samba 4 server (VM in a new hardware). Join it to the existing domain - Promote this server as BDC, migrate the DNS, DHCP - Demote the old Samba box as Domain Controller, leave the Shares in the old server Phase2: - Take a copy of the new samba DC VM and test NT4 to AD migration using the classic upgrade The urgency is do get Phase1 done but Phase2 is approved. What we would like to know if conceptually the above makes sense and is doable? The bit we are not very sure about is Adding the BDC and demoting the PDC. Any suggestions will be appreciated. Thank you. RT
Hi Guys, Have not had any feedback on this. I found the following article but not sure if it is valid https://www.samba.org/samba/docs/old/Samba3-HOWTO/samba-bdc.html We have an upcoming project to migrate Samba first into a new Hardware then the AD migration.

For the Samba 'classic/nt4-like' mode just removing the 'domain master = no' makes it a PDC. You can even have multiple PDCs as long as they can't see each other over netbios, the protocol is so simple it doesn't really matter (unlike AD).
