A complete data migration strategy prevents a subpar experience that ends up creating more problems than it solves. Live systems experience downtime while data goes through ETL processing and transitions to the new database. It’s important to test the data migration design with real data to ensure the accuracy of the implementation and completeness of the application. Moving data from one system to another can be a complex process. In the case of assessing your staff, determine what skills and experience they already have to see if there might be a lack in data migration expertise.

The next step involves validation, where the data is tested before it is finally delivered to its destination. It involves a lot of preparation and post-migration activities including planning, creating backups, quality testing, and validation of results. The temporary setup provides the environment for that to happen.

As long as the established plan … Cleaning the data is the next part of the Migration Phase. Less successful migrations can result in inaccurate data that contains redundancies and unknowns. The bulk of the data migration work is done in the workspace called “Data management.” As solution modeling takes place, integration design documents are written in order to identify parts of the solution that can be sectioned off into a deliverable unit. However, BALANCE DATA only changes the replica distribution among the machines. Without a competent data migration plan, businesses can run over budget, end up with overwhelming data processes, or find that their data operations are functioning below expectations.
