Oracle to Snowflake Migration – without breaking what Oracle runs


Contact us

Every year your organisation runs analytics on Oracle is another year of escalating licensing costs. We migrate Oracle databases, Oracle E-Business Suite, and Oracle Fusion and Financials Cloud to Snowflake — re-architecting pipelines, schemas, and governance for an analytics-first cloud platform.

OUR EXPERIENCE

Is Your Oracle Environment Holding Your Analytics Back?

Your Analytics Are Locked Inside Oracle Infrastructure

Oracle was built for transactions, not analytics. As reporting workloads grow, they compete with operational queries for the same compute – driving costs up, slowing query times, and making it harder to give finance, operations, and data teams the access they need.

Oracle Licensing Costs Get High for Analytics Workloads

A large share of your Oracle licensing spend is now supporting analytical and reporting workloads – dashboards, data extracts, finance reports, and business intelligence queries that don’t need to run on an OLTP database.

Your Oracle Cloud Data Doesn’t Reach Analysts Fast Enough

Oracle SaaS platforms can’t be accessed like a database. Finance and analytics teams waiting on stale ERP data — delayed by overnight extracts, manual exports, or brittle integrations — miss the real-time visibility that close processes, forecasting, and operational reporting require.

Your AI and Advanced Analytics Roadmap Is Blocked

Snowflake Cortex AI, Snowpark, and the data sharing capabilities your data science team wants to use require data to be in Snowflake — governed, clean, and structured for analytics. The migration is the prerequisite, not the destination.

OUR METHOD

Our Method — Migrate Oracle to Snowflake Without Breaking What the Business Runs On

We don’t just “lift and shift” your Oracle data into Snowflake. We treat migration as an architectural program — assessing every object, designing the right ingestion patterns, and building a governed Snowflake environment your teams will actually trust. Our approach makes sure you reach the decision to decommission Oracle analytics with confidence, not risk.

01

Assess the Full Oracle Footprint

We inventory schemas, PL/SQL logic, materialized views, workload patterns, Oracle Fusion and Financials Cloud integration paths, and downstream analytics dependencies before a single pipeline is built. Every object gets a decision: migrate, rationalise, or retire. This is where realistic timelines come from — not after the project has already started.

02

Design for Snowflake, Not Just Compatibility

We redesign schemas and transformation layers for Snowflake’s columnar, analytics-optimised architecture — not as a copy of Oracle. PL/SQL logic moves out of the database and into governed dbt transformation layers and pipeline orchestration. Ingestion tooling is selected to serve the architecture: GoldenGate or Snowflake Openflow for near real-time CDC, managed ELT for broader source coverage.

03

Validate Before You Decommission

Oracle stays live as the authoritative source until Snowflake passes automated reconciliation and finance stakeholder sign-off. Cutover is planned around your financial close calendar. No Oracle analytics are retired on a project schedule — only when parity is confirmed and the business says it’s ready.

END-TO-END CAPABILITIES

From Oracle Assessment to Snowflake Production — Full-Cycle Migration Delivery

From the initial audit to the final switch-over, we handle the heavy lifting.

We are specialists in data engineering and migrations. We assess the environment, design the target Snowflake architecture, build the pipelines, and manage the validation before migration is complete.

Assessment Icon

Oracle Assessment & Migration Scoping

We inventory your Oracle schemas, objects, workloads, and downstream dependencies — including Oracle Fusion and Financials Cloud integration paths. Every object is classified by migration approach and business criticality. Output: a realistic scope, phased delivery plan, and effort estimate based on your actual environment.

Architecture Icon

Snowflake Architecture & Schema Design

We design the target Snowflake environment from the ground up: raw, standardised, and curated layers; star schema transformations from Oracle’s normalised models; clustering key strategy; warehouse sizing; and the governed dbt transformation framework that replaces PL/SQL logic.

Engineering Icon

ETL Pipeline & CDC Replication Engineering

We build the ingestion pipelines that move Oracle data into Snowflake reliably, continuously, and at scale. Bulk historical load via cloud storage stages and Snowpipe. Near real-time CDC via GoldenGate or the Snowflake Openflow Connector. Managed ELT where appropriate. Pipelines are monitored, alertable, and built with documented SLAs.

Integration Icon

Oracle Fusion & Financials Cloud Integration

For Oracle SaaS, we navigate the available integration options — vendor export services, REST and SOAP APIs, and specialist connectors — to land ERP data reliably in Snowflake. We handle multi-ledger and multi-currency structures, incremental update patterns, schema drift, and the downstream data models that finance and reporting teams depend on.

Security Icon

Security, Governance & Compliance Design

We map Oracle roles to Snowflake RBAC, implement dynamic data masking and column-level security for sensitive data, and build the data lineage documentation required for SOX, GDPR, HIPAA, and CCPA. Governance is designed into the migration architecture before the first pipeline goes to production.

Validation Icon

Parallel Validation & Cutover Management

We manage the dual-run period with automated data reconciliation, financial balance checks, and structured sign-off from data and finance stakeholders. Cutover windows are planned around your financial close calendar. Oracle analytics are decommissioned when parity is confirmed — not when the project timeline says so.

OUR STEPS

A Clear Migration Path — Oracle to Snowflake in Stages

Oracle Assessment & Inventory
We inventory your full Oracle environment — schemas, PL/SQL packages, materialized views, workload patterns, and downstream dependencies. Oracle Fusion and Financials Cloud integration paths are mapped separately. Every object gets a decision: migrate, redesign for Snowflake, or retire.
Outcome:
You know exactly what you have, what it will cost to move, and what can be retired — before a single pipeline is built or a budget is committed.
Target Architecture Design
We design the target Snowflake environment: data layers, star schema transformations, warehouse sizing, clustering strategy, and ingestion tooling selection. The dbt transformation framework that replaces Oracle PL/SQL logic is defined here. Architecture drives tooling decisions.
Outcome:
A governed, analytics-optimised Snowflake architecture that justifies the migration investment — not a replica of Oracle in a cloud database.
Pipeline & Replication Build
We build the ingestion pipelines that move Oracle data into Snowflake continuously and at scale. Bulk historical load via cloud storage stages and Snowpipe. We integrate via APIs and specialist connectors handling multi-ledger, multi-currency, and incremental update patterns.
Outcome:
Production-ready pipelines with monitoring, alerting, and documented SLAs — not proof-of-concept jobs that break when data volumes or schemas change.
Parallel Validation
Oracle stays live as the authoritative source while Snowflake is validated in parallel. Automated reconciliation compares balances, row counts, and key metrics between both platforms. Financial data is validated against the same measures your finance team uses for close sign-off.
Outcome:
The confidence to decommission Oracle analytics on evidence — not on schedule pressure or project milestone dates.
Cutover & Decommission
Cutover windows are planned around your financial close calendar and regulatory reporting cycles. BI tools are switched to Snowflake-backed connections with validated outputs. Oracle analytics infrastructure is decommissioned incrementally as each domain confirms parity.
Outcome:
A clean Oracle analytics decommission, a live Snowflake production environment, and a cost structure that reflects what you actually use.

    FAQ

    Frequently Asked Questions about Oracle Migrations

    Is Oracle to Snowflake migration a lift-and-shift of tables?

    Rarely, and almost never for complex Oracle environments. The tables are the straightforward part. The real scope lies in the business logic embedded in PL/SQL packages, materialized views, triggers, and database jobs — none of which has a direct Snowflake equivalent.

    Beyond the logic layer, Oracle schemas are typically built for transactional workloads and need redesign for Snowflake’s columnar, analytics-optimised architecture. Organisations that attempt a pure table migration usually discover these gaps once reports start returning wrong numbers against the new platform.

    How do you integrate Oracle Fusion and Oracle Financials Cloud with Snowflake?

    We assess your specific Fusion and Financials Cloud modules, identify which integration pattern fits your latency and coverage requirements, and build pipelines that handle multi-ledger structures, multi-currency behaviour, incremental updates, and schema drift in a predictable, governed way.

    How do we handle the Oracle to Snowflake migration without disrupting financial closes?

    We plan cutover windows explicitly around your financial calendar — avoiding major transitions during month-end, quarter-end, or year-end close periods, and during key regulatory reporting cycles. During the migration program, Oracle remains the authoritative source for financial data until Snowflake has passed reconciliation and sign-off from finance stakeholders.

    We do not decommission Oracle-based reporting until balance checks confirm parity. For Oracle Financials Cloud and Fusion ERP data, we design the reconciliation process around the same metrics your finance team uses for close sign-off.

    How long does an Oracle to Snowflake migration typically take?

    It depends on Oracle environment complexity, data volumes, the presence of Oracle SaaS sources, replication latency requirements, and the number of downstream analytics consumers. A focused migration of a single Oracle database with well-understood schemas and no Oracle SaaS involvement can be delivered in 3 to 5 months including assessment, pipeline build, parallel validation, and cutover.

    A full enterprise migration covering multiple Oracle databases, Oracle Fusion or Financials Cloud, near real-time CDC pipelines, and a governed Snowflake analytics layer typically runs 12 to 20 months as a phased program. The assessment phase produces a realistic timeline for your specific environment — we do not give generic estimates.

    Will existing BI reports and dashboards break during the migration?

    If they are connected directly to Oracle, yes — that is the point. Migrating reporting consumers to Snowflake-backed semantic models is part of the program, not a follow-on task. We assess existing BI dependencies (Oracle BI, Power BI, Tableau, or other tools) during the scoping phase and plan their transition alongside the data migration.

    For regulated or business-critical reports, we validate outputs from Snowflake against Oracle before switching connections. Reports that cannot be moved during the initial migration phase remain Oracle-connected until their transition is explicitly scheduled and validated.
