48 business units migrated from legacy systems into Oracle Fusion

Data migration is a critical part of any large transformation program - Arguably, it's the most complex part.

When a major UK public sector healthcare organisation set out to migrate years of Oracle R12 ERP data across 48 business units into Oracle Fusion Cloud, they needed more than a capable team.

They needed a platform that could handle large volumes, messy source data, complex transformation logic - without putting their core operations at risk.

They chose eAppSys and our DMOne™ platform.

The challenge was significant. Source data quality issues needed to be resolved without disrupting live operations. Historical data, including unusual objects like attachments, debtor notes, and AP holds had to be preserved and migrated cleanly.

Business units needed to be consolidated and remapped from the old structure into the new Fusion design. And the scope kept growing, because confidence in DMOne™'s capabilities kept growing alongside it.

Here's what made the difference:

  • DMOne™ handled the full Extract-Transform-Load-Reconcile cycle from a single cloud-based platform, with built-in rules, validations, and data masking - no stitching together of separate tools.
  • Our team took end-to-end ownership. From mapping workshops through iterative ETL cycles to cutover - One team, Complete accountability.
  • Source data quality issues were addressed during the ETL process itself, not as a separate pre-project, saving weeks of elapsed time.
  • Scope expanded mid-project - a sign of confidence, not scope creep. The client added additional object types because the platform proved it could handle them cleanly.

If you're planning an Oracle R12 to Fusion Cloud migration and want to understand how DMOne™ can de-risk your data workstream, let's talk.
