Almost one third of the Dutch population has a fibre optic connection, also called Fibre to the Home (FttH). Fibre is currently the fastest and most reliable Internet technology. It consists of strong and flexible wires that are able to transport light signals over long distances. With such fibre optic connections, information is transmitted from one place to another when pulses of light are sent through an optical fibre and can reach Internet speeds of 500 Mb per second. In an ideal situation, all copper in the networks would be replaced by fiber. However, such an operation would be too expensive to complete all at once, so therefore, it would not be a feasible solution. However, it is also possible to replace parts of the copper network by fibre. For example, the extension of Fibre to the Curb could significantly increase the bandwidth, compared to services offered over a copper cable starting at the Central Office. Furthermore, for this extension, less costs are also involved compared to an extension of Fibre to the Home. On the other hand, the extension to a total fibre network will reach a higher bandwidth compared to an extension of Fibre to the Curb.

In this presentation, different heuristic methods and two migration models are proposed to obtain a good migration schedule in an acceptable computation time. A migration schedule contains for every migration year per location which topology and technology combination should be active.
