37.5 Million Directories Migrated With the Final Sync in 48 Hours for a Fortune 10 Tech Giant

For a Fortune 10 US-based technology company, the task of migrating billions of files from NetApp’s Infinite Volume to a Flex Group on the same cluster posed significant challenges. With a tight cutover window of 48 hours and millions of directories containing millions of files to be moved, the company sought a reliable solution. The answer came in the form of Data Dynamics Mobility Module, an efficient data migration software that not only met the complex requirements but also ensured optimal throughput and accuracy during the process.

Business Need

A Swift and Precise Data Migration

  • Migrating Billions of Files: A mammoth task of moving billions of files from one storage system to another within the same cluster.

  • Meeting Cutover Window: A challenging cutover window of 48 hours only to complete the entire migration.

  • Syncing Incremental Updates: Ensuring that incremental updates in the files were seamlessly synced during the migration.

  • Optimizing Throughput: Achieving optimal data transfer speeds while maintaining accuracy and efficiency.

Challenges Faced

Overcoming File System Updates and Glitches

  • Constant File System Updates: Ongoing updates to the file system demanded additional efforts in comparison and synchronization during migration.

  • Strict Cutover Window: The tight 48-hour window left no room for delays or inefficiencies.

  • Previous Tool Limitations: The previous migration tool was unable to handle incremental copies efficiently, causing delays and glitches in the process.

  • Optimizing Throughput: Striking the right balance between fast data transfer and accuracy posed a challenge.
