When you are planning to replace your Mediation Server, you need to acquire a new server that meets the recommended minimum requirements, including arranging for IP addressing for the new server, building the new host server hardware, and joining the new server to the Active Directory domain. Ensure that you choose server hardware that can support your expected call load, that has two network interface cards, and that is 64-bit. Virtualization of the Mediation Server is not recommended. In addition, arranging for discrete IP addressing before you start can make the new server deployment run more smoothly.
