/mcpBefore you begin Make sure that the old phone is in the "Unregistered" state before you proceed with migration. You can plug the new phone into the network, wait until you get the phone migration or provisioning prompt and start the migration process. Once the migration is successful, the device re-registers with the users phone configuration data. Procedure Step 1 Connect the new Cisco IP Phone to the network. Step 2 Select the option 2 to replace an existing phone. Note If the Administrator hasn't configured Activation Code based device onboarding or phone migration is done on the 11.5(1)SU8 version of Unified Communications Manager which doesn't support activation code, the phone displays the screen to enter the primary extension. Step 3 Enter the primary extension number of your phone. Step 4 Enter your PIN. Migration starts after a successful authentication. After successful migration, the phone restarts with configuration settings migrated from your old phone. Note Consider a scenario where the On-premise Onboarding Method option is selected as Auto registration in the Device Defaults Configuration page. While performing the phone migration, if you press either the EXIT or BACK button when an error message is displayed, it takes you directly to the initial phone migration screen after a possible expected delay. This delay is due to the phones trying to re-register to the Unified CM as auto-registration is disabled in the Unified Communications Manager server. Note If there are more than one device for the user with the same primary extension, the user will be prompted to choose the device to be migrated. For more information, see Phone Migration Service—User Assigned with Multiple Devices, on page 712. Phone Migration Service COP File If you are running any version of the Unified Communications Manager starting from 11.5(1) until 11.5(1)SU7, install Phone Migration Service COP file (ciscocm-migration-service-11-5-1.zip) to get the Native Phone Migration feature support. As part of the COP file installation, ‘Tftp restart’ service is done automatically for Unified Communications Manager. If you plan to upgrade the Unified CM after Phone Migration Service COP file installation, ensure that you upgrade your Unified CM server to a release version that has native support for the Native Phone Migration feature.
