Best method for on prem DHCP when migrating all servers to Azure?

Tags: Cloud

I’m moving all servers from our branch on prem sites to Azure including the domain controllers which provide dns/dhcp for clients and office phones. We have fortigate FWs which can provide dns and dhcp. What’s the best way to align the dhcp addresses with dns? Forward dns to the azure dns servers? We do have an existing on prem DC with dns at our main site we also can forward dns to. Thanks a lot.

I would never advise such a move. I’m reading https://docs.microsoft.com/en-us/answers/questions/219168/migrating-on-prem-dhcp-server-to-azure.html and agree with what’s there.

Technically it is possible to have DNS/DHCP server on Azure but for that it may require to have On prem to Azure S2S VPN connectivity or Express route.
For connection the On prem site to Azure following link may be helpful : https://github.com/dmauser/DHCPServer-On-Azure

Also for on prem AD & DNS (DC) synchronization with Azure AD, Azure AD Connect can be used.
