The following steps will convert multiple phones from Enterprise to MPP firmware.
Prerequisites
• Set up the DHCP option and file server for MPP.
• Upgrade the enterprise phones to firmware version 12.5 with Unified CM.
Example: sip88xx.12-5-1SR1-4
1. Upgrade the enterprise phones to the E2M migration load from the Unified FM by specifying the load name (for example,
sip88xx.TLexE2M-11-2-3C12) and load server (for example, 10.23.45.67).
2. Allow the phones to boot up with the E2M migration firmware and find DHCP option 160.
• The device requests $PSN.xml (for example http://10.23.56.67/8851-3PCC.xml
• Each phone replaces the $MAU macro with its uppercase MAC address to retrieve the device-specific license file to unable
the upgrade to the requested MPP firmware.
