Configuration data associated with a router is converted. A selector tool identifies a first port of a first router having first data lines, and identifies a second port of a second router to receive the first data lines to be migrated from the first port. The first router and the second router use different, incompatible configuration data formats. A data transceiver captures first port configuration data associated with the first port of the first router, and a configuration data converter is to identify a type of interface associated with the captured first port configuration data and convert the captured first port configuration data from a first format compatible with the first router to a second format compatible with the second router based on the identified type of interface. A conversion file generator generates a configuration file containing the converted first port configuration data in the second format.
