Things to consider before migration to new hardware
- Are you going to keep same DC host name ?
- Are you going to use same IP address?
- If you are changing your name and IP if it will have influence on your network ( Firewall Roles etc..)
- Is the server DHCP server
- Is the server root CA? – I’m not sure if you can migrate Enterprise Root CA – May be Restore from Backup
- Is the server Global Catalog ?
Preparation steps
- Make full Backup of your Active Directory
- Install new server and join it to your domain
- Install DNS Service (use active directory integrated zone) that will allow DNS records to replicate
- Install DHCP service on. Migrate DHCP database. Read MS Article
- Migrate FSMO roles to new installed server: See transfer FSMO rules
- Set New server as Global Catalog if you don’t have other DC in your site that operates as Global Catalog: Read MS Artcle
Remove old machine from domain
- Demote the domain controller by running DCpromo
- Disjoin the server from the domain.
Hope It helped
