Data Migration Project Management and Standard Software - Experiences in A valoq Implementation Projects

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 comers 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. lt 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.
