Subscriber data migration with dual provisioning

One or more non-transitory computer readable storage media encoded with instructions that, when executed by one or more processors, cause the one or more processors to perform a method comprising operations including:

• storing, in a first subscriber data server, subscriber data for each of a plurality of wireless devices, the subscriber data enabling wireless communication services for the plurality of wireless devices in a wireless network;
• determining to migrate the subscriber data from the first subscriber data server to a second subscriber data server;
• upon determining to migrate the subscriber data, initiating a migration process to migrate the subscriber data from the first subscriber data server to a second subscriber data server by copying the subscriber data from the first subscriber data server to the second subscriber data server;
• and
• provisioning one or more new wireless devices for the wireless communication services in the wireless network;
• and
• while copying is occurring during the migration process and while provisioning the one or more new wireless devices for the wireless communication services in the wireless network, adding new subscriber data for the one or more new wireless devices to the first subscriber data server and adding the new subscriber data for the one or more new wireless devices to the second subscriber data server.

A system comprising:

• a first subscriber data server that stores subscriber data for each of a plurality of wireless devices, the subscriber data enabling wireless communication services for the plurality of wireless devices in a wireless network;
• a second subscriber data server;
• and
• a controller configured to:
• determine to migrate the subscriber data from the first subscriber data server to the second subscriber data server;
• upon determining to migrate the subscriber data, initiate a migration process to migrate the subscriber data from the first subscriber data server to a second subscriber data server by copying the subscriber data from the first subscriber data server to the second subscriber data server;
• provision one or more new wireless devices for the wireless communication services in the wireless network;
• and
• while copying is occurring during the migration process and while provisioning the one or more new wireless devices for the wireless communication services in the wireless network, add new subscriber data for the one or more new wireless devices to the first subscriber data server and adding the new subscriber data for the one or more new wireless devices to the second subscriber data server.

A computer-implemented method comprising:

• storing, in a first subscriber data server, subscriber data for each of a plurality of wireless devices, the subscriber data enabling wireless communication services for the plurality of wireless devices in a wireless network;
• determining to migrate the subscriber data from the first subscriber data server to a second subscriber data server;
• upon determining to migrate the subscriber data, initiating a migration process to migrate the subscriber data from the first subscriber data server to a second subscriber data server by copying the subscriber data from the first subscriber data server to the second subscriber data server;
• provisioning one or more new wireless devices for the wireless communication services in the wireless network;
• and
• while copying is occurring during the migration process and while provisioning the one or more new wireless devices for the wireless communication services in the wireless network, adding new subscriber data for the one or more new wireless devices to the first subscriber data server and adding the new subscriber data for the one or more new wireless devices to the second subscriber data server, wherein the migration process comprises at least one state that includes at least one processing track selected from a group including
• a communication profile data comprising a template that determines which wireless communication services are available to a given wireless device of the plurality of wireless devices, and which wireless communication service providers the given wireless device can use when roaming,
• roaming restriction data that maps wireless communication service providers with respective communication profiles,
• switchover access point name data for gateways between the wireless network and the Internet to be associated with the second subscriber data server,
• switchover roaming restriction data that associates the roaming restriction data with the second subscriber data server, and
• switchover communication profile data that associates the communication profile data with the second subscriber data server.
