Data migration (en-US)
Data migration is the process of transferring data from one system, database, or storage environment to another—such as moving from an on-premises database to the cloud, upgrading an application, consolidating multiple databases, or changing data formats and structures. The goal is to preserve data integrity, accuracy, and usability in the new environment while minimizing downtime and risk.

Key activities
Typical steps include: (1) planning and scoping (what data, from where, to where, and why), (2) assessing data quality and compatibility (schemas, formats, constraints), (3) mapping and transforming data (field-by-field alignment, normalization/denormalization, format conversions), (4) extracting, loading, and validating (ETL/ELT), (5) testing (reconciliation, performance checks, end-to-end verification), (6) cutover and rollback planning, and (7) post-migration monitoring and documentation. Common challenges include incomplete records, inconsistent formats, duplicate data, and differences in business rules between source and target systems.

FAQ
FAQ 1) What’s the difference between data migration and data integration? Data migration moves data to a new target system; data integration connects or synchronizes data across systems over time. 2) How do teams ensure data accuracy? They use data mapping, validation rules, reconciliation counts, checksums, and sample-based or automated record comparisons. 3) How long does a data migration take? It varies widely based on data volume, complexity, and testing requirements—from days to months.
