13. The apparatus of claim 8 , wherein the first graphical map, the second graphical map, and the probability score are concurrently shown within a single graphical user interface.
8. An apparatus comprising: a bus; a storage device connected to the bus, wherein the storage device contains computer readable code; a communications unit connected to the bus; and a processing unit connected to the bus, wherein the processing unit executes the computer readable code to: receive a user entered first search term for the enterprise industry model; electronically search a first domain of instance data of the enterprise industry model for first nodes matching the first search term; generate and displaying a first graphical map that shows one or more first nodes that match the first search term and edges which interconnect the one or more first nodes with other nodes in accordance with relationships defined in the first domain; receive a user entered second search term for the legacy model; electronically search a second domain of instance data of the legacy model for second nodes matching the second search term; generate and displaying a second graphical map that shows one or more of the second nodes that match the second search term and edges which interconnect the one or more second nodes with other nodes in accordance with relationships defined in the second domain; calculate a probability score representing a probability that a first one of the matching second nodes is capable of implementing the function of a first one of the matching first nodes; and graphically indicate a connection between and the probability score for the first one of the matching first nodes and the first one of the matching second nodes.
