EISBERG
Migrations · Legacy enterprise

Modernize off legacy. Without the multi-year project.

Teradata, Oracle, SQL Server, Netezza, Greenplum, Vertica. Bring the workload — DDL, code, governance, BI dependencies — and land it on a modern, open-format, customer-owned data platform. The translation is automated. The validation is parallel-run. The cutover is on your timeline.

Platforms we migrate from

Six legacy enterprise warehouses, one modernization path.

Teradata

Enterprise data warehouse modernization including BTEQ, stored procedures, and SQL Assistant workloads.

Oracle Exadata

PL/SQL translation, materialized view conversion, and partitioning strategy migration.

Microsoft SQL Server / Synapse

T-SQL translation, SSIS pipeline migration, and Azure-aware deployment.

Netezza / IBM PureData

Legacy appliance retirement with lift-and-shift to open-format storage.

Greenplum

Distributed Postgres migration with workload-shape preservation.

Vertica

Column-store migration with engine-equivalent performance characterization.

The migration path

Six weeks from discovery to parallel-run.

  1. Week 1

    Discovery

    Inventory the workload — DDL, views, stored procs, ETL pipelines, governance policies, BI dependencies. Baseline measured cost and latency.

  2. Weeks 2-3

    Translate

    Automated DDL and code translation. Manual review of edge cases. Governance policy mapping into the unified policy plane.

  3. Weeks 3-4

    Land data

    Stream data into Apache Iceberg in your object storage. Validation against source-system row counts and aggregates.

  4. Weeks 4-6

    Parallel run

    Run Eisberg alongside the legacy warehouse. Reconcile output, measure cost and latency, build confidence.

  5. Week 6+

    Cutover

    Direct production traffic to Eisberg. Decommission legacy infrastructure on your timeline. Continued lineage and audit trail across the boundary.

What you keep

Continuity that survives the cutover.

Your business logic — translated, not rewritten
Your governance policies — mapped into the unified policy plane
Your BI dashboards — pointed at Eisberg without rebuild
Your lineage — extended forward, not reset
Your historical data — landed in open format, queryable as it was
Your team's skills — SQL, dbt, and infrastructure-as-code transfer 1:1

Bring us your legacy workload.

Send a workload sample, an EXPLAIN plan, or a quarter's worth of bills. We will model the same workload on Eisberg and produce a side-by-side cost, latency, and governance comparison — with the math, not the marketing.
