Perform data validation checks on the data before and after the migration to ensure data completeness, consistency, accuracy, and integrity.

Assume that the data in the old system is accurate and complete, and directly transfer it to the new system without any validation.

Use a data profiling tool to analyze the data in the old system and identify any issues with data quality before the migration.

Ignore the data quality during the migration process and focus only on the technical aspects of the migration.
