Data migration is the process of moving data from one location to another, one format to another, or one application to another.
Generally, this is the result of introducing a new system or location for the data. A business driver is usually an application migration or consolidation in which the legacy system was replaced or supplemented with a new application that will share the same dataset. You can navigate to online resources and find out more information about data migration.
These days, data migration which often begins as the company moves from local infrastructure and applications to cloud-based storage and applications to optimize or change their company.
Why has Data Migration Seen as Hard and Risky?
The short answer is "gravity data." Although the concept of gravity data has been around for some time, the challenge becomes more significant as the migration of data to the cloud infrastructure. In summary, the data that gravity is a metaphor that describes:
- How interesting data other data to it as it grows
- How data is integrated into the business
- How will the data be adjusted from time to time
To move applications and data into a more favorable environment, Gartner recommends "decipher" data and applications as a way to overcome gravity data.
By making the time at the beginning of the project to sort out the data and the complexity of the application, companies can improve their data management, enabling application mobility, and improve data governance.
The main problem is that each application complicate data management by introducing elements of the application logic to the level of data management, and each is indifferent to the subsequent data use cases.
