Why is selecting tables important during data migration?

Selecting tables during data migration is crucial primarily to ensure that only the required data is migrated. This is important for several reasons.

When migrating data, it is vital to focus on the information that is necessary for the new system or applications. By filtering out irrelevant or unnecessary tables, you can streamline the migration process and reduce the overall volume of data being moved. This targeted approach not only conserves resources, such as time and bandwidth but also minimizes potential issues related to data integrity and coherence.

Furthermore, migrating only the required data helps in maintaining clarity and organization within the new environment. It reduces the complexity involved in post-migration tasks, such as data validation and integration, making it easier to achieve the desired outcomes in the new system.

These benefits underscore the importance of selecting specific tables that align with application requirements and operational needs during the data migration process.
