A phased migration involves transferring data in smaller, manageable segments rather than attempting to move the entire dataset simultaneously. This approach is particularly effective in minimizing disruptions to operations, as it allows for testing and validation of each segment before proceeding to the next. By breaking the migration process into phases, organizations can address any issues that arise in a controlled manner and ensure that data integrity is maintained throughout the process.

This method contrasts with migrating an entire dataset at once, which could lead to significant operational risks, including potential loss of data or extended downtimes. Archiving all data before migration typically refers to a data cleansing or backup strategy rather than a phased migration technique. Additionally, transferring only essential data may not capture the full scope of what a phased migration entails, as it suggests selective rather than segmented movement of data.
