Not sure you really need to do anything, at least initially. So right now the domain 2 clients (192.168.101.x) are receiving DHCP addresses from their local DC or some DHCP server on domain 2 that has a scope setup for the 192.168.101.x address range, correct? When you flip these clients over to the domain 1 domain, they will still be physically on the same side of the VPN, so they will continue to get DHCP addresses from the same box they were getting from before.
My guess is that you want to flip them to a DHCP server in domain 1 at some point after the migration? If so something like this should work. On the DC that sits on the domain 2 side of the VPN, or some other box you designate, setup DHCP and configure a scope identical to how it currently is for the box that's currently handing it out for 192.168.101.x, but don't activate it yet. Then when the migration is complete, de-activate the scope on the old DHCP server, and activate it on the new DHCP server. Should be that simple. Unless your network is more complex.

We have two domains, I'll call them domain 1 and 2, they are in two physical locations. Domain 1 is on subnet 192.168.100.1, domain 2 is on 192.168.101.1. There is a VPN tunnel between the two that connects the two domains and allows us to have a trust between the two. We want to eliminate domain 2. We already have a domain 1 DC on the domain 2 LAN. The issue we are having is how to get the desktops in domain 2 after the migration to domain 1 to continue on subnet 192.168.101.1 so the VPN tunnel continues to function how it is and so we don't run out of IP addresses. I've hit a roadblock on how to handle this and I would love some ideas.
