Replacing a Cisco Unity Server Without Failover
**Cisco Unity 4.x licenses are associated with the MAC address on the network interface card (NIC). Get updated license files that reference the MAC address of the NIC in the new server.
Note that if the existing Cisco Unity server is running version 3.1(x) and if the replacement server does not have a port for the system key, you must upgrade to the currently shipping 4.x version before you replace the existing server. Cisco Unity 4.x does not require a hardware key, so the availability of a port for the key is not an issue.
