Finally, the data will be loaded into the new system. About the data migration process. While it’s true that a form of testing already took place during the Migration Phase, this testing ensures that everything went well. This is in contrast to data integration where data is active in both, or several, places. At a high level, migrations function in the following way: By backing up the data, you’ll have something on hand to restore any data you accidentally lose. Not sure about your data? Data migration is also necessary when deploying another system that sits alongside existing applications. The pressure, though, can be intense, as the business operates with one of its resources offline. The test will make sure that there aren’t any connectivity problems and that the data arrived at its proper destination securely and in its correct form. Once those tests are done, there’s still no guarantee that you have a problem-free system on your hands. Data tools that simplify migration are more efficient and cost-effective.
