Session border control migration

A system comprising:

• a first session border controller (SBC) device;
• and
• a second SBC device to:
• receive one or more fully-qualified domain names (FQDNs) associated with the first SBC device during a migration of one or more customer premises equipment (CPE) devices from the first SBC device to the second SBC device,
• the one or more CPE devices being within a customer network,
• update domain name system (DNS) server entries for the one or more FQDNs,
• send information based on the DNS server entries to the one or more CPE devices, and
• receive a session initiation protocol (SIP) session signal from one of the one or more CPE devices,
• the first SBC device being to:
• send, to a dynamic host configuration protocol (DHCP) server, configuration information, for the one or more CPE devices, to change a first IP address associated with a fist domain name system (DNS) component of the first SBC device to a second IP address associated with a second DNS component of the second SBC device.

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by at least one processor, cause the at least one processor to:
• provide, to a new session border controller (SBC) device, provisioning information to migrate one or more customer devices within a customer network from an original SBC device of a provider network to the new SBC device,
• the provisioning information including one or more fully-qualified domain names (FQDNs) associated with the original SBC device;
• provide, to the original SBC device, a dynamic host configuration protocol (DHCP) update,
• the DHCP update including instructions to change a domain name system (DNS) address from a first Internet Protocol (IP) address associated with the original SBC device to a second IP address associated with the new SBC device;
• and
• provide, to the original SBC device and at a time after updating of DNS server entries is complete, instructions to delete the one or more FQDNs from the original SBC device.

A method comprising:

• receiving, by a first session border controller (SBC) device, configuration information, for customer devices, to change a first IP address associated with a first domain name system (DNS) component of the first SBC device to a second IP address associated with a second DNS component of a second SBC device when the customer devices are migrated from the first SBC device to the second SBC device, the customer devices being within a customer network;
• providing, by the first SBC device and to a dynamic host configuration protocol (DHCP) server in the customer network, the configuration information, for the customer devices, to change the first IP address associated with the first DNS component of the first SBC device to the second IP address associated with the second DNS component of the second SBC device;
• receiving, by the second SBC device, provisioning information to migrate the customer devices from the first SBC device to the second SBC device, the provisioning information including one or more fully-qualified domain names (FQDNs) associated with the first SBC device;
• updating domain name system (DNS) server entries for the one or more FQDNs based on the provisioning information;
• and
• providing, to the customer devices, DNS entry updates for the one or more FQDNs based on the updating of the DNS server entries.
