What is Data Migration?

In this post, I will explain What is Data Migration? and What are the reasons for Data Migration? Data migration is the process of transferring data between data storage systems, data formats or computer systems. A data migration project is done for numerous reasons, which include

1. Replacing or upgrading servers or storage equipment

2. Moving data to third-party cloud providers, 

3. Website consolidation

4. Infrastructure maintenance

5. Application or database migration 

6. Software upgrades

7. Company mergers 

8. Datacenter relocation

Data migration may impact business operations when it creates extended downtime, compatibility and performance issues. Organizations use various strategies to minimize such impacts, including effective planning, technology, implementation and validation.

Planning, migration and validation are key to effective data migration. Planning requires a clear understanding of design requirements, such as scheduling, replication requirements, hardware requirements, data volume and data value. Prior to data migration, an organization typically communicates methodologies, installs migration software and configures required hardware.

Automated data migration minimizes human intervention and application downtime and enhances migration speed. Migration documentation facilitates tracking and reduces future migration costs and risks.

Once data migration is complete, an organization validates statistics to determine data accuracy. Finally, data cleaning facilitates improve data quality via the removal of unnecessary or repetitive data.
