Data Migration and Transformations

The systems we build and maintain contain vast volumes of data that is both sensitive and has significant financial value. Our experience and track record of handling data migration from varied systems is envied by many competitors in the market.


The transition from the original REC Registry for the Clean Energy Regulator, including all historic and current certificate information and account details; saw over 100 tables migrated, including manual data processes with over 500 million rows of information. An innovative and significant certificate ranges transformation was applied during the migration to support aggressive performance requirements derived from a 20 year forecast of system usage. We also support the Clean Energy Regulator’s data warehousing requirements and have implemented a secure bridge between the REC Registry’s Oracle RAC database and their Microsoft SQL Server based internal systems.

As a federal government project, the ACMA Numbering System has strict non-functional requirements around security, accessibility, and performance. These requirements are comprehensively met through a combination of off-the-shelf and in-house solutions, and are thoroughly tested by the Quality Assurance (QA) team.
