Keys to Successful Data Migration, by
Sandy Shin
With the increased reliance on information technology (IT) across all industries and the ever-increasing pace of technological development, data migration has become a major concern for most businesses. Companies perform data migrations for a number of reasons, such as consolidating collections, improving the quality of data, adding functionality and efficiency, and moving to new software solutions.
Historically, data migration has been a costly and somewhat risky endeavor, but with modern IT infrastructure and a proper migration plan, companies can avoid transitional difficulties entirely. Unfortunately, many businesses continue to experience expensive migration problems due to a lack of planning.
The first step in a successful data migration involves understanding the information to be migrated. Source data should be profiled to gain an understanding of content and structure, taking into consideration the type of data in each field and dependencies between data in different fields. In addition, data that is replicated or overlaps between sets should be identified.
Next, data should be organized into a mapping structure that will allow it to be moved to the correct location in the new system. Such a map will require the data to be represented by a normalized relational model that completely translates the relationships in the data from the old system to the new one. New structures should also be added to increase performance in the new system and address additional concerns. Finally, a set of protocols for transforming data from one format to the other can be established.
A proper understanding of these general principles can ensure that a business will be able to conduct a data migration relatively quickly and with little or no loss of data. Ideally, such a migration should also add functionality and remove problems inherent in the original data structure.
