DHCP Switchover between two domains.

Hello - I need an assist to perform DHCP switch-over between 2 different domains.

1. Currently the DHCP scopes are configured in DHCP cluster for domain NET.AAA.COM.
2. Client machines also in NET.AAA.COM.
3. Now, I need to move the scopes out from cluster servers and need to configure the same in another server which is in BB.NET domain.
4. Still the client machines will be in NET.AAA.COM domain only.
5. Both domains NET.AAA.COM and BB.NET are having trust relationship between them and we can login to servers using either domain accounts to both domain servers.

Please suggest an solution to perform this migration. Thanks in advance!
