Data Migration Plan

Creating a data migration plan (or data migration process) is crucial when you’re moving data from one system to another, whether it’s due to system upgrades, data center relocation, or other reasons. Komprise Elastic Data Migration is focused on unstructured data migrations. Here’s a general outline for a data migration plan:

Define Objectives and Scope:

  • Clearly state the reasons for migration.
  • Define the scope of the migration (what data will be migrated, and what won’t).

Assessment of Current Data:

  • Analyze the existing data to identify dependencies, relationships, and potential issues.
  • Document the data types, formats, and volumes.

Risk Assessment:

  • Identify potential risks and challenges.
  • Plan for contingencies in case of data corruption, loss, or other issues.

Resource Identification:

  • Identify and allocate necessary resources (human, technical, and financial).

Select Migration Method:

  • Easy-path-to-the-cloud-600x600-1

    Choose the appropriate migration method (parallel, serial, big bang).

  • Decide whether to use a manual or automated approach.

Data Mapping:

  • Create a mapping between the source and target systems to ensure data consistency.

Data Cleansing:

  • Cleanse and sanitize data before migration to improve data quality.
  • Remove duplicates, obsolete, or irrelevant data.

Data Backups:

  • Perform a complete backup of the existing data before starting the migration.

Data Migration Testing:

  • Conduct thorough testing in a controlled environment.
  • Test for data integrity, accuracy, and completeness.

Communication Plan:

  • Communicate the migration plan to all stakeholders.
  • Establish communication channels for updates and issue resolution.


  • Train the personnel involved in the data migration process.
  • Provide documentation for reference.

Data Migration Execution:

  • Implement the migration plan.
  • Monitor the data migration process closely for any issues.


  • Verify the data integrity and completeness post-migration.
  • Compare the migrated data with the source data.

Post-Migration Support:

  • Provide support for users to adapt to the new system.
  • Address any issues that arise after migration.


  • Document the entire migration process for future reference.
  • Include any lessons learned and recommendations for future migrations.

Performance Monitoring:

  • Monitor the performance of the new system.
  • Address any performance issues that arise.


  • Conduct a post-implementation review.
  • Close out the migration project.

The specifics of the data migration plan will depend on the unique aspects of your organization, the systems involved, the scale of the migration and the type of data being migrated. Regularly update and refine the plan based on feedback and outcomes during the migration process.
