Demoting a domain controller

I need to demote my domain controllers because we migrated into another domain.  The issue is my DC has DHCP running on it.  Is there a way I can demote it and still keep DHCP on it as a member server in a different domain without having to migrate DHCP?

No, you need to migrate DHCP server as in domain environment DHCP server must be authorized by AD. If it is not then it cannot issue leases.

You may join that decommissioned DC as a domain member to another domain and authorize DHCP or migrate DHCP database from the old box to the new one in target domain

migrating DHCP isn't too painful.  I recommend doing it after hours though.
