The Minor Planet Center curates and disseminates a catalog of around 400 million astrometric observations of over 1.3 million Solar System bodies. In addition, we compute and distribute orbits, ephemerides, identifications and associated metadata in both modern and legacy formats. This vast and heterogeneous set of data and data products is utilized by a similarly vast and heterogeneous user base. This, combined with the need for prompt and continuous operations, has led to a highly complex collection of legacy software. In this poster, we describe two examples from recent years of our attempts to modernize our systems:

Where Are My Observations (WAMO), an application/API that allows users to track the processing status of their submissions.

Near-Earth Object Confirmation Page (NEOCP), used by the community to identify new nearby asteroids and comets.
