I wanted to take a more resilient approach to my home network and therefore decided to move off of the Raspberry PI’s that run Pi-hole and Samba AD DC.
I decided to virtualize the Samba installations in a container, and separate the Pi-hole from the Active Directory instances. This in itself provides a more resilient situation, but in the virtualized case I can also create regular backups for the nodes, and maybe later move towards a cluster.
This post will focus on the steps from the Samba AD DC side, it will not detail the Proxmox-setup – I will cover that in a separate post!
The TL:DR; summary of this process is as follows:
- Backup the domain controller (I know I won’t do this, but it is the prudent thing to do)
- Join the new domain controller to the domain
- Sync the sysvol ACL
- Transfer FSMO roles
- Demote “old” domain controller
