Editing Data migration (section)

===Project versus process===
There is a difference between data migration and [[data integration]] activities. Data migration is a project through 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 simultaneous migrations. 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.

Data integration, by contrast, is a permanent part of the [[Information technology architecture|IT architecture]], and is responsible for the way data flows between the various applications and data stores—and is a process rather than a project activity. Standard ETL technologies designed to supply data from operational systems to data warehouses would fit within the latter category.<ref name="KingData16">{{cite web |url=https://solutionsreview.com/data-integration/data-integration-vs-data-migration-whats-the-difference/ |title=Data Integration vs. Data Migration; What's the Difference? |author=King, T. |work=Solutions Review - Data Integration |publisher=LeadSpark, Inc |date=17 August 2016 |access-date=20 July 2018}}</ref>
