Migrating MS 2019 AD, DHCP, DNS & DFSR to MS 2022? (alien.top)

Hello,

Been a few years since I have done this so the process is a bit fuzzy for me.

In my lab I have a single 2019 std server with AD, DHCP, DNS and DSFR.

I've built a new 2022 std server and joined it to my domain.

Am reading plenty of guides but cannot fund a single guide to move all the services my current 2019 serves to 2022.

What I am unsure about is when to move/migrate DHCP and DNS.

Am I correct to follow this path.

Migrate 2019 AD to 2022

Demote 2019

Install DHCP and DNS on 2022 then Migrate 2019 DHCP and DNS scope/records to 2022

Remove DHCP and DNS on 2019

Delete/decom 2019 server (after all seems well).

Thank you and cheers in advance.

edit: or another thought, follow the AD migration guide and then just install/create new DHCP and DNS services on the new 2022?

Add ADDS, dns & dhcp role Reboot Promote to domain controller & reboot Move FSMO roles to the new DC Demote old DC (Don't rush these three steps. Take your time) Now you can just export the dhcp config and import it on the new server, then adjust your dhcp scopes in the server to only contain your new DC's IP as a dns server, & dhcp forwarders on your router to forward to the new DC's IP instead of the old one Shut down the old server once you're happy it's all working
