STORAGE MIGRATION

This migration involved transferring over 40 terabytes of data from an EMC storage system to an IBM storage solution for a major Fast-Moving Consumer Goods (FMCG) company.

Challenges:

• Ensuring minimal downtime during the migration to prevent business disruption.
• Maintaining data integrity and consistency.
• Handling a large dataset efficiently.

Approach:

• Assessment & Planning: Evaluated the source and target storage architecture, identified dependencies, and planned the migration timeline.
• Data Replication & Migration: Used tools like IBM Spectrum Control or host-based replication to transfer data.
• Validation & Cutover: Ensured all data was accurately transferred, performed testing, and switched to the new storage.
• Outcome: Successful migration with no data loss and minimal impact on business operations.

This involved migrating customer workloads from IBM storage to NetApp, possibly due to a change in vendor preferences, performance upgrades, or cost optimisations.

Challenges:

• Compatibility between IBM storage formats and NetApp.
• Optimising NetApp features like deduplication and snapshots post-migration.
• Migrating without disrupting critical applications.

Approach:

• Used NetApp migration tools such as SnapMirror or Cloud Sync for seamless data transfer.
• Staged migration for large data sets to avoid network congestion.
• Thorough validation and performance tuning on the new platform.
• Outcome: Smooth transition to NetApp storage with improved data management capabilities.

Migration from HP storage to IBM storage for a well-known clothing retail chain, likely to enhance performance, scalability, or cost efficiency.

Challenges:

• Migrating data from a retail environment with 24/7 operations.
• Ensuring compatibility between HP and IBM storage architectures.
• Addressing security and compliance requirements.

Approach:

• Used IBM storage migration tools such as IBM Storage Insights or host-based migration.
• Implemented a phased approach, starting with non-critical data before migrating active workloads.
• Conducted rigorous post-migration testing to confirm system stability.
• Outcome: A successful upgrade to IBM storage, enhancing the retailer’s ability to manage high transaction volumes effectively.
