Workday HCM: Data Migration Testing Simplified
📌 Introduction: Why Data Migration Testing Matters?
Workday HCM serves customers across 14+ industries, including Finance, Healthcare, Retail, Education, and Communications. Each company has unique data structures and compliance needs, but they all must migrate critical employee information—such as job records, payroll details, benefits, and performance history—from their legacy systems into Workday.
This is where Data Migration Testing comes in!
✅ Ensures migrated data is complete, accurate, and usable in Workday.
✅ Prevents data loss, corruption, or misalignment.
✅ Aligns with Workday’s best practices for Extract, Transform, Load (ETL) operations.
🚀 Without proper testing, organisations risk data integrity issues, compliance violations, and payroll errors!
🔎 What is Data Migration Testing in Workday?
Data Migration Testing ensures that all HR data is successfully transferred from the legacy system (e.g., SAP, Oracle, or spreadsheets) into Workday without errors. This process consists of three main stages:
📌 Extract – Export legacy HR data. 📌 Transform – Reformat and cleanse data to fit Workday’s structure. 📌 Load – Import data into Workday using EIB (Enterprise Interface Builder) or custom integrations.
📊 Workday Data Migration Testing Coverage Matrix
A Data Migration Testing Coverage Matrix helps track whether all key HCM data components have been validated before moving forward. Here’s an example:
| HCM Data Component | Test Scenario | Expected Outcome | Pass/Fail |
| Employee Records | All employees appear in Workday | Full list matches legacy system | ✅ Pass |
| Job Profiles | Positions align correctly | Titles & levels match original data | ✅ Pass |
| Payroll Data | Salaries and benefits are correct | Payroll reflects accurate compensation | ✅ Pass |
| Absence Balances | PTO & sick leave match legacy system | All balances transfer correctly | ✅ Pass |
| Security Permissions | Managers access correct employee data | No unauthorized access | ✅ Pass |
🔹 Using a matrix ensures systematic validation and avoids missing key data fields!
📌 Common Workday Data Migration Testing Types
🛠 1. Data Completeness Testing
✅ Ensures all required data fields are migrated.
✅ Compares record counts between legacy and Workday systems.
🛠 2. Data Accuracy Testing
✅ Verifies no data was altered incorrectly.
✅ Uses sample records to validate data mappings.
🛠 3. Data Integrity Testing
✅ Detects duplicate, missing, or misaligned data.
✅ Ensures reporting structures remain intact.
🛠 4. Data Security Testing
✅ Confirms role-based access controls (RBAC) are applied correctly.
✅ Protects sensitive employee data (e.g., salaries, Social Security numbers).
🛠 5. End-to-End (E2E) Data Flow Testing
✅ Validates data across Recruiting, Onboarding, Payroll, Absence, and Learning modules.
✅ Ensures Workday processes function correctly with migrated data.
📈 Comparing Data Migration Testing Volumes in Workday Deployments
Migration testing varies based on project complexity. Let’s compare:
📌 Workday Rapid Deployment (Minimal Customisation)
👉 Uses mostly standard Workday configurations.
👉 Less migration complexity, so testing effort is lower.
| TESTING PHASE |
| 🔹 DATA MIGRATION TESTING (50%) |
| 🔸 SYSTEM TESTING (30%) |
| 🔻 UAT (20%)INTEGRATION TESTING (30%) |
| 🔻 FUNCTIONAL E2E TESTING (20%) |
| ______________________________________________________ |
📌 Full-Scale Workday Implementation (Highly Customised)
👉 Involves custom integrations & complex data transformations.
👉 Requires extensive validation & issue resolution before go-live.
| TESTING PHASE |

📌 More customisation = More extensive testing required!
🔍 Key Validation Endpoints in Workday Data Migration
✔ Run Data Reconciliation Reports – Compare legacy & Workday records.
✔ Use Workday Business Processes – Test HR workflows (e.g., promotions, terminations).
✔ Verify Payroll & Compensation Data – Ensure salaries, deductions, and benefits match.
✔ Conduct User Acceptance Testing (UAT) – HR teams validate real-world scenarios in Workday.
📌 Tip: A final data audit before go-live prevents post-migration surprises!
🚀 Best Practices for Workday Data Migration Testing
✔️ Perform Pre-Migration Data Cleansing – Fix duplicate & incorrect records before migration.
✔️ Use a Coverage Matrix – Ensure all HCM data units are tested.
✔️ Engage SMEs & Data Owners Early – Get sign-offs before loading data into Workday.
✔️ Automate Reconciliation Where Possible – Reduce manual validation time.
✔️ Test in Iterations – Run multiple migration test cycles to catch issues early.
🔚 Conclusion: Ensuring a Smooth Workday Go-Live
Data Migration Testing is a critical step in Workday HCM adoption. Without proper testing, organisations risk data corruption, compliance violations, and payroll errors. Following Workday best practices ensures a smooth transition with minimal disruptions.
📌 Key Takeaways:
✅ Workday follows an ETL approach for data migration.
✅ Testing ensures data completeness, accuracy, and security.
✅ Migrated data should be validated before, during, and after loading into Workday.
