Data migration
There is a difference between data migration and data integration activities. Data migration is a project by means of which data will be moved or copied from one environment to another, and removed or decommissioned in the source. During the migration (which can take place over months or even years), data can flow in multiple directions, and there may be multiple migrations taking place simultaneously. The ETL (extract, transform, load) actions will be necessary, although the means of achieving these may not be those traditionally associated with the ETL acronym.
Value Migration (book)
Value migration as a concept is a flow of economic value from outmoded, obsolete businesses towards the others with superior business designs. The latter ones are better positioned to create utility and comfort for customers. In this book, the author describes the skills that managers and owners need to identify and to capture these value shifts. He posits that the change in a business landscape is, in fact, inevitable and identifies seven patterns of value migration that managers should know.
