The setup is this
6 NT4 servers with Exchange 5.5
server 1 is the main server, sends and receives to the internet.
Server 2 & 3 connect via an ISDN modem
Server 4,5 & 6 are connected sites on the WAN.
I want to REPLACE Server 1 with a new Dual p3 system, what is the best way to get this new server into the Mail system. and take over all the roles of server 1 so that this old server can be retired ?
