Data Migration

Data Migration

Data migration projects are short-lived but inevitable because a new information system can be introduced into the business for a variety of reasons.

Data migration is a perennial exercise in enterprise computing. With the introduction of a new information system (ERP/CRM) in the business, data existing in the legacy system must be moved into a new improved target system. Data migration projects are short-lived but inevitable because a new information system can be introduced into the business for a variety of reasons. Often, it is the deterioration of existing legacy systems over a period that leads to heavy maintenance and eventually minimal or no vendor support. Mergers, acquisitions, and demand for more functionality and improved usability are other mundane business scenarios requiring data migration.

Whatever the reason could be, a new information system can not be operational with an empty database. The legacy data, generally large in amount must be first loaded into the new system before its go-live moment. More often than not, data models of old and new systems are fundamentally different. The primary objectives of the data migration project are to extract the data from the legacy system, transform it into the desired target data model, and finally to upload it into the new information system.
