Abstract: When a bank implements a new core banking platform, it must simultaneously migrate its data from the old platform into the new one. We identified three main dimensions for data migration. They make up the corners in our conceptual data migration project management framework: the data migration triangle. The first dimension demands scripts as deliverables, which actually transform and migrate the data. The second, and too often neglected, dimension is the delivery of data. It requires that the scripts run together reliably and on time in a complex environment with many dependencies. Dimension three addresses quality assurance. We describe methods for checking whether all necessary data is migrated and whether the data is migrated correctly. In contrast to previous work, we focus on technical issues from a project manager’s perspective. We explain what data migration project managers have to manage and why.
