Conclusion

The data migration workstream plays a supporting role within the project, whose task is to ensure that integration or cutover testing begins or the system goes live by delivering operational data in a defined volume, quality, and by a certain deadline. This underscores that the project work of the data migration workstream cannot be planned and executed within the framework of “standard” project phases due to its distinct tasks. Introducing the concept of data migration phases resolves this issue by enabling the distribution of migration activities in the necessary sequence and timing, clear shaping the data migration process, while still maintaining control over the entire project, since each migration phase is equipped with controllable deliverables, thus ensuring the project's overall manageability.
