Migrate between database technologies
Database migration
We refactor code, convert schemas, and plan cutover—so applications keep running while the foundation changes.
Modernize legacy data platforms
Data platform migration
We translate proprietary code into cloud-native equivalents—preserving the business logic your teams depend on.
Rebuild pipelines for the modern stack
ETL and pipeline migration
We re-engineer data flows on modern frameworks—turning migration into a chance to eliminate technical debt.

Cross-cloud migration
We manage cross-cloud migrations across any provider combination so you don't lose momentum.
Rehost quickly, then optimize
Lift-and-shift migration
Sometimes the fastest path to value is leaving the data center first. We rehost with minimal code changes, then build a phased roadmap to modernize in the cloud.
Wayfair saves millions and boosts performance with a strategic migration
Pythian supports the acceleration of data insights facilitating ROI-focused migration.
Pythian partnered with Wayfair to migrate thousands of SQL applications and petabytes of data to Google Cloud—resulting in 23 percent faster browsing, 30 percent less fraud, and millions in cost savings. The migration accelerated data insights and empowered the global eCommerce company to streamline data management at scale.
Data migration that achieves modernization with zero-disruption
A proven data migration framework built on 25+ years of migrating the world's most complex data environments.
We catalog workloads, dependencies, and business logic across your environment. The output is a migration readiness assessment with no surprises later.
We recommend the right path based on workloads, budget, and strategic goals—grounded in ROI modeling, not vendor loyalty.
We design target-state architecture with detailed cutover plans and rollback procedures—so the business keeps running throughout.
We migrate data, pipelines, and business logic—refactoring code and validating integrity at every step. Dual-run validation confirms identical results before cutover.
We validate that migrated data matches the source semantically—not just structurally—and train your teams. Post-launch managed services keep your environment optimized as it evolves.

Data migration consulting services frequently asked questions (FAQ)
Security is built into every phase of our migration process. We establish clear policies for data access, handling, and classification from day one, along with encryption, metadata management, and fine-grained access controls. During migration, we maintain strict data integrity validation and audit trails so your sensitive information is protected throughout the transition—not just after go-live. For regulated industries, we remap existing security frameworks (Kerberos, Ranger, platform-native IAM) to cloud-native equivalents, ensuring zero gaps in compliance coverage.
Every engagement starts with a strategic assessment that maps your migration to specific business outcomes—whether that's reducing total cost of ownership, accelerating time-to-insight, or enabling new analytics and AI capabilities. We track quantifiable milestones throughout delivery, and our phased approach means you start seeing returns on high-value workloads early in the migration. Post-launch optimization services ensure your new platform continues to deliver value as your data volumes and business needs evolve.
We develop detailed cutover plans with rollback procedures and temporary synchronization architectures that keep both source and target systems running in parallel during the transition. Dual-run validation confirms the new environment produces identical results before we cutover. Our migration timeline is tailored to your business calendar—avoiding peak periods and delivering phased milestones so critical workloads are never at risk.
