We are building a new network and need to use ADMT to migrate our user and computer accounts to the new domain. Unfortunately as a result of politics more than anything else, we aren't able to build a simple firewall rule to allow the domain controllers to talk.
What are the options for using ADMT between separate networks. My initial though would be to use a split tunnel VPN in the new network to connect to the old domain. I haven't tested this though, and have no idea if it would work.
Any suggestions are welcome.
