Stuttgart Airport with its former handling subsidiary Stuttgart Ground Services, which now has become member of the AHS group, and top- system, can look back on a very long co-operative partnership. Alrea- dy in 2002, the topsystem software had been implemented for both airport and handling department and has been continually used until now. It was one of the first projects with the initial web-based version. Actually, in this project the seasonal flight scheduling module was developed, which is the direct ancestor of the most recent release 4.0 currently featured in the software family. Beyond the flight scheduling the software also covers the complete commercial processes for both aeronautical billing and the invoicing of ground handling operations.

One reason for the remarkable longevity of the system is its great flexibility. The platform-independent technologies used guaran- tee a long-term compatibility, while the modular structure allows to upgrade or expand the functionalities exactly according to individually changing requirements at any time. Thus, it was decided for the soft- ware migration project that the legacy modules for flight scheduling, contract management, service recording and invoicing still meet the current requirements while need for action focused on other areas: in preparation for the implementation of a collaborative decision making system (CDM), to which topsystem will also contribute, a range of technologies working in the background had to be adapted.

As an initial step it was necessary to migrate the topsystem soft- ware from 2002 to modern server technologies and software tools. In this process, the airport replaced the aged IBM-AIX servers with Windows server technology. Due to the platform-independence of topsystem's software solutions, the complete migration went without a hitch and was finished extremely quick. In the course of the re- installation, upgrades were implemented for some of the software modules in use. For example, the IATA message parser was replaced with a modern technology which makes maintenance easier. Further- more, the message processing was changed from SITATEX to import via e-mail.

One of the highlights of the system overhaul was the new interface for the Tower Flight Data Processing System (TFDPS). In preparation for the upcoming CDM project, a bidirectional message exchange with the German air traffic control, "Deutsche Flugsicherung (DFS)", was implemented. The information exchange is now based on the modern ADEXP format, which is a crucial for the CDM implementation.
