Oracle Database migration services for mission-critical transformations
Stabilize
Exadata environment assessment and stabilization
We assess your Exadata environment to identify performance bottlenecks, security vulnerabilities, and licensing exposure—then create a reliable, benchmarked baseline.
Optimize
Performance, licensing, and pipeline optimization
We tune Exadata performance across SQL execution, Smart Scan, and RAC while eliminating licensing waste through audit-ready cost analysis. Legacy ETL is replaced with modern orchestration so your Oracle environment runs leaner, faster, and better governed.
Migrate and modernize
Oracle Cloud and cloud-native migration
We migrate Exadata to OCI, Autonomous Database, or cloud-native platforms like Snowflake, BigQuery, and Databricks. Vendor-neutral guidance ensures you take the path that delivers the most value.
How we work with you
Planning to extract value
We assess your Exadata environment across performance, storage, and cluster health. For aging hardware approaching end of support, we identify vulnerabilities and build a remediation plan. The goal: Stabilize mission-critical workloads and extract maximum value while we plan the path forward.
Strategizing business case
Every Exadata modernization is also a licensing project. We analyze your licensing position—unused options, core count right-sizing, BYOL strategies, and audit risk. This analysis directly informs the migration strategy and is the prerequisite for an accurate business case.
Vendor-neutral guidance
We recommend the right path—Oracle Cloud, cloud-native exit, or hybrid—based on ROI, workload characteristics, and business reality. For mixed environments, we design the workload separation architecture. Vendor-neutral guidance grounded in value, not vendor loyalty.
Stabilizing mission-critical strategies
We orchestrate large-scale data extraction at terabyte-to-petabyte scale, accounting for HCC decompression during staging. Dual-run synchronization maintains consistency during the transition period. Cutover planning includes rollback strategies so mission-critical operations are never at risk.
Modern orchestration
We combine automated tooling with expert manual refactoring for the complex 20–40 percent that automation can't handle—the advanced packages and dependencies where generalist firms hit a wall. Simultaneously, we replace legacy ETL with modern orchestration on Airflow, Fivetran, and dbt.
Production-grade data platforming
We deliver modern BI dashboards, self-service analytics, and production AI pipelines on your new platform. Post-migration, we provide 24/7 ongoing support plus Oracle licensing compliance monitoring to ensure a clean transition.
Modernizing a legacy Oracle Exadata data warehouse for a global retailer
How Pythian turned aging Exadata into a cloud-native analytics and AI platform.
A global multi-brand retailer with 2,000+ stores across North America and Europe ran its data warehouse on aging Oracle Exadata hardware approaching end of support. Holiday traffic exposed critical bottlenecks, Oracle licensing consumed over 40 percent of data infrastructure spend, and business teams waited hours for reports. Pythian migrated analytics workloads to Google BigQuery, stabilized OLTP on Oracle Cloud, and delivered real-time insights, production AI, and seven-figure annual savings.
Pythian: The enterprise migration leader
Database modernization migrations from Oracle
Oracle to PostgreSQL
Migrate Oracle databases to PostgreSQL to reduce licensing costs and transition to a flexible open-source relational database platform. This migration typically includes schema conversion, PL/SQL refactoring, and application compatibility testing.
Oracle to SQL Server
Transition Oracle Database workloads to Microsoft SQL Server to integrate with Microsoft’s enterprise data ecosystem and simplify management within Windows-based application environments.
Oracle to MSSQL
Modernize legacy Oracle environments by migrating to Microsoft SQL Server (MSSQL), leveraging automated schema conversion tools and data migration frameworks to preserve data integrity and application functionality.
Cloud and platform modernization from Oracle Database
Oracle Database to Snowflake
Migrate Oracle data warehouse workloads to Snowflake’s cloud-native platform to enable elastic scaling, simplified infrastructure management, and high-performance analytics.
Oracle Database to Databricks
Modernize Oracle environments by migrating data pipelines and analytical workloads to the Databricks Lakehouse platform for unified data engineering, analytics, and machine learning.
Oracle Database to AWS
Re-platform Oracle workloads to AWS services such as Amazon RDS, Amazon Aurora, or Amazon Redshift to integrate with AWS cloud infrastructure and analytics services.
Oracle Database to Azure
Move Oracle workloads to Azure environments using Azure SQL services or Oracle Database@Azure to integrate with Microsoft’s enterprise cloud ecosystem.
Oracle Database to Google Cloud
Migrate Oracle databases to Google Cloud using services such as Cloud SQL, AlloyDB, or BigQuery to enable advanced analytics and AI capabilities.

Oracle Exadata consulting services frequently asked questions (FAQ)
PL/SQL is the single deepest source of migration complexity in Oracle Exadata environments—codebases often span hundreds of thousands of lines built over decades. We use a combination of automated tooling (Google Batch SQL Translator, Ispirer, Ora2Pg) and expert manual refactoring. Automated tools typically handle 60–80 percent of simpler constructs. The remaining 20–40 percent—advanced packages, autonomous transactions, pipelined functions, bulk collect operations, cursor sharing, and DBMS_* dependencies—requires hands-on refactoring by engineers who understand both the Oracle source and the cloud-native target. This is precisely where generalist firms hit a wall, and where Pythian's dual fluency in Oracle and modern platforms makes the difference.
ROI comes from multiple sources depending on your path. For customers optimizing in place, we typically identify significant licensing savings by uncovering unused options and right-sizing core counts—Oracle licensing costs often consume 30–50 percent of total Exadata TCO. For customers exiting to cloud-native platforms, a 30–60 percent TCO reduction is a typical target when you factor in eliminated licensing fees, reduced support costs, and the shift from capital expenditure to operational expenditure. Beyond cost, organizations gain elastic scaling without purchasing additional racks, self-service analytics without Oracle Analytics licenses, and AI/ML capabilities without expensive advanced analytics and in-memory options. Our phased approach means you start seeing returns on high-value workloads early—not just at the end of the migration.
Oracle's licensing model—per-core, multiplied by core factor, with separate charges for each option like RAC, partitioning, advanced security, and in-memory—creates significant compliance risk during migration. We build licensing analysis into the migration plan from day one. That includes BYOL optimization for customers moving to OCI or multicloud Exadata, audit risk mitigation strategies during the dual-run transition period, and license harvesting plans for customers reducing or exiting their Oracle footprint. We also monitor compliance post-migration to ensure you don't inadvertently trigger audit exposure. Every Exadata migration is a licensing project, and we treat it that way.
It depends on your workload characteristics, Oracle investment depth, and strategic direction. Oracle Cloud (Exadata Cloud Service, Cloud@Customer, Autonomous Database) is a strong choice for organizations that want to preserve their PL/SQL codebase and Oracle skill sets while gaining cloud elasticity and modern AI capabilities like Oracle AI Database 26ai. Cloud-native platforms (BigQuery, Snowflake, Databricks) are better suited for organizations ready to decouple from Oracle's ecosystem and gain transparent pricing, serverless scaling, and modern BI and AI integration. A hybrid approach—migrating analytics to cloud-native while keeping mission-critical OLTP on Oracle—is increasingly common and often the most pragmatic first step. Pythian provides vendor-neutral assessment based on ROI modeling and workload analysis, not vendor loyalty. Unlike Oracle's own consulting arm, we're equally capable of executing any of the three paths.
