Pythian turns proprietary complexity into competitive advantage
Production-ready Teradata solutions for every stage of your journey.
Optimize and tune
High-performance Teradata operations
We analyze your Teradata environment to identify bottlenecks and optimize performance—from BTEQ scripts and stored procedures to TASM settings. For environments approaching end-of-support, we stabilize workloads and buy time for strategic planning.
Ensure 24/7 stability
Ongoing Teradata support
24/7 monitoring, DBA services, and health checks keep your Teradata environment stable and secure. As experienced Teradata DBAs become harder to find, Pythian fills the skills gap—so you get reliability without building a specialized in-house team.
Exit to cloud-native
Cloud-native platform migration
We specialize in low-risk exits to BigQuery, Snowflake, Fabric, and Azure. Our engineers refactor proprietary BTEQ scripts, translate Teradata SQL extensions, and redesign data models for cloud-native distribution—so your business logic survives intact.
Modernize pipelines and orchestration
Data engineering and automation
We re-engineer Teradata's proprietary ETL utilities into modern pipelines using Airflow, Fivetran, and cloud-native orchestration—turning the migration into an opportunity to eliminate years of technical debt.
Govern and secure your data estate
Data strategy and governance
We remap Teradata's access controls and workload management to cloud-native governance frameworks. Security, compliance, and cost controls are built in from day one.
Unlock analytics and AI
Production analytics and AI enablement
We transform static reports into real-time dashboards and enable self-service BI. Then we integrate ML workflows directly into your platform—unlocking analytics and AI that legacy Teradata couldn't support.
Modernizing a legacy Teradata estate for enterprise analytics and AI
Pythian migrated a decade-old Teradata warehouse to BigQuery without disrupting 24/7 operations.
This organization built its business on Teradata's reliability. But as customers demanded real-time analytics and AI-driven insights, the legacy environment couldn't keep pace. Pythian delivered a full-stack modernization—cutting infrastructure costs by 45 percent and unlocking capabilities Teradata alone couldn't support.
A Teradata modernization approach that ensures a zero-disruption migration
Data ecosystem analysis
We assess your full Teradata estate—scripts, stored procedures, ETL jobs, and data models. For environments approaching end-of-support, we stabilize mission-critical workloads and ensure operational continuity while we plan the path forward.
Establishing critical prerequisites
We catalog every workload, pipeline, and policy, then map the dependencies between them. This complete picture is the critical prerequisite for any migration—and the step where most programs fail without deep Teradata expertise.
A roadmap for your priorities
We recommend the right path—BigQuery, Snowflake, Fabric, Synapse, VantageCloud, or a phased hybrid—based on your workloads and business priorities. Vendor-neutral guidance grounded in ROI modeling, with phased milestones to deliver quick wins first.
Securing data integrity without disruption
We refactor proprietary scripts, translate Teradata-specific SQL, re-engineer ETL utilities, and redesign data models for cloud-native distribution. Dual-run validation ensures data integrity and zero business disruption.
Resource freeing support
We deliver modern dashboards, self-service analytics, and AI-ready pipelines on your new platform—plus 24/7 ongoing support so your team can focus on extracting value, not managing infrastructure.

Govern and control your data estate
Data strategy and governance
We remap Teradata's granular access controls and governance metadata to cloud-native frameworks—defining ownership policies, ensuring compliance, and aligning data investments with business priorities so your new environment is secure and cost-controlled from day one.
Build resilient, modern pipelines
Data engineering consulting
We re-engineer Teradata's proprietary ETL stack—FastLoad, MultiLoad, TPT, and BTEQ batch jobs—into resilient, observable data flows built on Airflow, Fivetran, dbt, and cloud-native orchestration. Your pipelines become scalable, testable, and production-grade.
Operationalize AI at scale
Production AI
From data locked in Teradata to production-ready AI. We integrate ML workflows using BigQuery ML, Vertex AI, MLflow, or Snowpark ML—deploying models into business workflows that legacy infrastructure couldn't support.
Teradata consulting services frequently asked questions (FAQ)
Teradata's proprietary ecosystem—BTEQ scripting, FastLoad, MultiLoad, TPUMP, Parallel Transporter (TPT), and SQL extensions like QUALIFY, SET table uniqueness, and system-specific functions (COLLECT STATS, EXPLAIN, SHOW)—creates migration barriers that most firms underestimate. Automated translation tools can handle a portion of standard ANSI SQL, but proprietary syntax, embedded business logic, PI/SI-dependent data models, and Teradata-specific data types (BYTE, VARBYTE, INTERVAL) require manual refactoring by engineers who understand both the source and target platforms. Pythian's team has deep expertise in the full Teradata stack and has successfully re-engineered complex code bases for migrations to BigQuery, Snowflake, Fabric, and Synapse. We validate every refactored component against the source system with parallel dual-run testing, so you know the business logic and data integrity survived the move.
The ROI from Teradata modernization comes from multiple sources. Infrastructure cost savings are often the most immediate win—customers moving from on-premises Teradata to cloud platforms have seen significant cost reductions by eliminating hardware maintenance and proprietary licensing. Beyond cost reduction, organizations typically gain faster query performance, elastic scalability, reduced operational complexity, and the ability to enable self-service analytics and production AI that weren't feasible on the legacy platform. Our phased approach means you start seeing returns on high-value workloads early in the engagement—not just at the end.
It depends on your workload characteristics, strategic direction, and budget. Teradata VantageCloud is a viable path for organizations that want to preserve existing Teradata SQL, stored procedures, and workload management while gaining cloud scalability and hybrid deployment. Cloud-native platforms like BigQuery, Snowflake, Fabric, or Azure Synapse are better suited for organizations ready to fully decouple from Teradata's proprietary ecosystem and gain serverless scaling, modern BI integration, and AI-ready infrastructure. A third option—phased hybrid—lets you migrate high-value workloads to cloud-native platforms first while maintaining Teradata for lower-priority jobs during the transition. Pythian provides vendor-neutral assessment based on workload analysis and ROI modeling, not vendor loyalty.
End-of-support deadlines are a common trigger for Teradata modernization—and one of the most time-sensitive. Pythian starts with a security vulnerability assessment and performance health check of your current environment, then builds a remediation plan to stabilize mission-critical workloads while we plan and execute the migration. Our dual-run methodology means production workloads continue running on the existing Teradata system while we validate the target environment in parallel—so the business never goes dark, even under tight hardware end-of-life timelines. We also bridge the growing Teradata skills gap with 24/7 managed services, ensuring continuity as experienced DBAs become harder to find.
