Clean Oracle data migration for an HVAC controls provider — via partner
Delivered as part of a partner engagement, ETHX ran the Oracle data conversion for a US HVAC controls and building-solutions provider — extracting, cleansing, mapping, and loading master and transactional data into Oracle Cloud with full reconciliation back to source.

* US HVAC controls & building-solutions provider — client anonymised at their request
The Challenge
- Legacy master and transactional data spread across inconsistent formats
- Duplicate, incomplete, and mis-mapped records that would corrupt Oracle Cloud if loaded as-is
- A fixed cutover window with no room for a failed load
- Every loaded balance had to reconcile 1:1 to the source system for audit
Our Approach
- Partnered with the prime organisation on a staged extract → cleanse → map → load pipeline
- Profiled source data and built cleansing and de-duplication rules with the business
- Loaded via Oracle FBDI and HDL with automated validation at each stage
- Ran mock conversions ahead of cutover, tuning against real volumes and error rates
- Reconciled every loaded object back to source with signed-off control reports
The Outcome
- Master and transactional data loaded cleanly into Oracle Cloud
- Every balance reconciled 1:1 to the source system — zero unexplained variances
- Cutover completed inside the planned window
- A repeatable, documented conversion pipeline the client can reuse
