Legacy Database Modernization

Legacy Database Modernization Guide

Legacy databases are often a choke point in todayโ€™s fast-moving digital landscape. They are costly to operate and maintain, they arenโ€™t scalable, and they present a growing security liability. As organizations advance in size and begin to implement cloud-first strategies, legacy databases are often not able to keep up with current demand.

Liberty to modernize legacy databases offers organizations the chance to gain more agility, improve performance, reduce operational costs, and achieve seamless compatibility within cloud-native environments. This document will explore the strategies, benefits, and best practices for modernizing legacy databases, and share how our Database Modernization Services help organizations with a seamless experience.

Modernize Legacy Databases

  • Performance & Scalability- Modern platforms offer high availability, elastic scaling, and improved query performance.
  • Security & Compliance– Legacy databases present vulnerabilities. Modern databases provide security features including encryption, IAM, and compliance certifications.
  • Cost efficiency– Move to a cloud provider or open-source solution, which reduces your licensing fees, hardware reliance, and maintenance costs.
  • Integration & Innovation– Perform analytics, AI/ML, automation, and create real-time data pipelines.
  • Business Continuity– Use resilient architectures for the future and to minimize downtime.

Strategies for Legacy Database Modernization

1. Rehosting (Lift-and-Shift)

This is basically just migrating the database as is to a cloud environment to achieve quick cost and performance benefits.

2. Replatforming

Migrate to a managed service (AWS RDS, Azure SQL, Google Cloud SQL) for reduced administration effort and with similar functionality.

3. Refactoring

Redesign the schemas, queries, and architecture to take full advantage of the modern capabilities offered by microservices, containers, and serverless.

4. Replacing with Cloud-native Solutions

Use fully-managed, cloud-native solutions like Aurora, Cosmos DB or BigQuery for the additional scalability and analytics capabilities they offer.

5. Hybrid Approaches

With mission-critical workloads, phase in the modernization effort through replication, dual-write, or cutover only when the new solution is fully adopted.

Best Practices for Legacy Database Modernization

  • Consider the thorough discovery of workloads, dependencies, and risk.
  • Ensure security and compliance from day one.
  • Leverage automated/migration tools to reduce downtime (AWS DMS, Azure DMS, Oracle GoldenGate).
  • Validate data integrity pre- and post-migration.
  • Put real-time monitoring and performance tuning in place.
  • Have a rollback plan in place for business continuity.

Benefits of Legacy Database Modernization

  • Faster performance & lower query latencies
  • Scalable architecture to support growing workloads
  • Lower costs (licenses and infrastructure)
  • Improved compliance & security posture
  • Access to modern analytics, AI/ML, and automation tools
  • Improved customer & user experience

Businesses gain competitive advantages through modernization via agility, cost savings, and improved data-driven decision-making.
