Data Mapping and Migration
Data Mapping and Migration
Move your HR and ERP data with confidence
Data is the single biggest risk in any HR or ERP modernization. A migrated record that is wrong produces a wrong paycheck, a wrong retirement computation or a rejected federal reporting submission, and legacy systems carry decades of organization-specific codes, history and workarounds.
Volitiion IIT runs data conversion as an engineering discipline: repeatable, auditable mock conversions rather than one-time loads. Because we have operated the PeopleSoft HCM and Financials systems organizations are migrating from, our teams know where the data comes from and how it behaves.
Our approach
- Profile and inventory: catalog every source (PeopleSoft, Oracle EBS, legacy HR systems, spreadsheets, position files) and measure completeness, validity and duplication.
- Cleanse at the source: work with HR and finance specialists to correct records before conversion, such as SSN and name mismatches, missing service computation dates, orphaned positions and invalid action history.
- Map and transform: field-level source-to-target crosswalks to the target data model and federal code sets (NOA, LAC, pay plan, bargaining unit), with transformation logic held in version control.
- Mock conversions: at least three full rehearsals, each measured against defined error thresholds, before production cutover.
- Reconcile and certify: record counts, financial totals (salary, leave balances, benefit elections) and sample-based specialist sign-off.
- Historical data strategy: decide what converts as active data and what moves to an archive or analytics store, so the new platform starts clean.
What we deliver
- Source-to-target mapping specifications and code-set crosswalks
- Extraction and transformation pipelines, and load files for Oracle HCM Data Loader and Workday
- Mock conversion results, error dashboards and defect remediation tracking
- Reconciliation and certification packages for go-live decisions
- Archive and retention design for data that does not convert
Platforms
From: PeopleSoft HCM and Financials, Oracle E-Business Suite, legacy and agency-specific HR systems.
To: Oracle HCM Cloud, the governmentwide Core HCM platform, Workday and Oracle Cloud ERP.
Staging and analytics: governed Databricks lakehouse environments for profiling, transformation lineage and reconciliation evidence.
