Data Migration
Moving stored data to another long term location or system, changing the format if necessary while preserving its content and meaning.
Details
Data migration must preserve not only values but relationships, context, metadata, dynamic functionality, and the meaning of the audit trail. Inspections cite comparisons limited to record counts and values, with no verification of searchability, linkage, time zones, units, or loss of the audit trail. Look at the migration strategy, mapping and transformation rules, the verification plan and reconciliation results, exceptions and approvals, and the decision to retire the source system.
