Ellucian Colleague to Workday Student Data Migration

This engagement migrates an institution's Ellucian Colleague deployment — running on UniData/Unix — to Workday Student, covering core student records, academic history, financial accounts, and person entities. The migration uses a three-phase ETL approach: a Staging phase extracts Colleague flat files and normalized relationships, a Transformation phase maps UniData field names and value sets to Workday's object model, and a Load phase pushes data via Workday Studio or Inbound Integration format.

The hardest part is reconciling Colleague's deeply nested, non-relational UniData structures with Workday's strict referential integrity requirements — especially for multi-term enrollment chains, program 版本控制, and financial obligation carry-forward — all while maintaining a frozen-cutover window and a fast-path rollback mechanism if validation fails.

Key field mappings between Colleague STUMS/PERSONS files and Workday Student Academic Record API payload:

<!-- Ellucian Colleague Source Fields -->
STUMS.STU_ID        → Student ID (Primary Key)
PERSONS.PERNME_FIRST  → Legal First Name
PERSONS.PERNME_LAST   → Legal Last Name
PERSONS.PERNAT_BIRTHDATE → Date of Birth
STUMS.STU_PIDM       → PIDM (Cross-file Join Key)
STUAC.STAC_PROGRAM    → Academic Program Code
STUAC.STAC_TERM       → Enrollment Term
STUCR.STCR_COURSE     → Course Reference (cross-listed)

Implementation pathway

Step by step

How we'd take this from discovery to a production-safe cutover — the phases, the canonical mapping, and the edge cases that bite.

This implementation pathway governs the staged extraction, transformation, and load (ETL) of student records, academic history, financial data, and person entities from the Ellucian Colleague UniData environment into Workday Student. The approach uses a landing-zone pattern with referential integrity validation at each phase, ensuring that foreign-key relationships (STU to ACAD.PROG, ACAD.PROG to ACAD.PLAN, etc.) are resolved before target records are committed. The migration executes in discrete phases with rollback capability and reconciled cutover.

Phases

Discovery and Source Audit: Inventory Ellucian Colleague UniData files (STU, STU.ADM, ACAD.PROG, ACAD.PLAN, ACAD.REC, PERSON, FIN.AID, CHARGE, PAYMENT, TRANSCRIPT). Extract record counts, identify null keys, orphaned foreign keys, and duplicate SKeys. Document data-quality thresholds; agree on a "loadable" vs. "exception" split with the Workday functional team.
Target Schema Mapping and Workday Sandbox Build: Map source file layouts to Workday Student business objects (Student, Academic Program, Academic Plan, Academic Record, Student Financial Application, Financial Aid Award, Student Payment). Build transformation rules in the staging layer (SQL or Informatica Cloud). Validate in a non-production Workday tenant using a subset of 500–1,000 seed records.
Staging and Referential Integrity Sequencing: Load PERSON records first (target: Worker object). Then load STU to create Student workers; link via Worker_ID to PERSON. Load ACAD.PROG before ACAD.PLAN; load ACAD.REC after both. Load FIN.AID and CHARGE only after confirming all referenced Academic_Program_ID values exist in Workday. Log each stage's row counts for reconciliation.
Data Cleansing and Enrichment: Standardize date formats (Colleague stores as DD/MM/YYYY or Julian; Workday expects ISO-8601). Decode Colleague lookup codes (e.g., STU.STATUS values) to Workday academic standing constants. Resolve name suffixes, preferred-name flags, and multiple SSN/TIN entries. Flag records with invalid addresses for manual remediation.
Validation and Reconciliation Report: Run Workday Student_Integration_Validation_Report (or equivalent functional report). Compare source counts per file against Workday committed rows. Verify GPA, cumulative credits, and financial-aid totals at the student level. Generate exception spreadsheets for records failing rule validation.
Parallel Run and Delta Capture: Freeze source data at a snapshot timestamp. In parallel, run the production load into Workday. Capture any new or changed records in Colleague that arrive after the snapshot in a delta table; plan a second delta load 24–48 hours post-cutover to capture in-flight admissions or registration activity.
Cutover and Go-Live: On cutover day, validate that all batch jobs have completed with zero fatal errors. Set Ellucian Colleague to read-only or suspend Student module transactions. Confirm Workday is authoritative for student data. Decommission or archive the legacy Colleague student files per data-retention policy.

Core Field Mappings

Ellucian Colleague Field	Workday Student Object	Workday Field	Notes
`STU.ID`	Student (Worker)	`Worker_ID`	Primary key; map to Workday-assigned ID or retain source value via ID mapping table.
`PERSON.LAST.NAME`	Worker	`Legal_Last_Name`	Map preferred name to `Preferred_Last_Name` if `PERSON.PREF.NAME` is populated.
`STU.ETHN`	Worker	`Ethnicity_Code`	Decode Colleague ethnicity codes to Workday EEOC constants.
`ACAD.REC.CUM.GPA`	Academic Record	`Cumulative_GPA`	Computed from ACAD.REC at load; recalculate post-load via Workday Academic Standing rules.
`ACAD.PROG.CIP.CODE`	Academic Program	`CIP_Code`	Cross-walk to Workday-supported CIP taxonomy version (2018 or 2022).
`FIN.AID.AWARD.AMT`	Financial Aid Award	`Award_Amount`	Load after ACAD.PROG; validate `Award_Year` against Workday Financial Aid Period.
`CHARGE.NET.AMT`	Student Payment	`Charged_Amount`	Reconcile sum of `CHARGE.NET.AMT` against Workday `Student_Balance` before closing.

Edge Cases

Duplicate SKeys: If the same student appears in STU with different STU.ID values (merged records), consolidate before load to avoid duplicate Worker rows in Workday.
Orphaned ACAD.PROG: ACAD.PROG rows referencing a STU.ID that does not exist in STU will fail Workday validation; isolate these in an exception file.
Future-Dated Enrollment: Colleague records with ACAD.REC.ENROLL.DATE in the future may bypass Workday enrollment validation rules; flag for manual academic-office review.
Financial Aid in Pending Status: Awards with FIN.AID.STATUS = "P" (pending) should not be loaded as active awards; route to a separate pending-load batch.
Address Format Mismatch: Colleague stores multi-line addresses in a single PERSON.ADDR field; Workday requires split Address_Line_1, Address_Line_2, City, State, Postal_Code; parsing logic must be validated against international addresses (non-US students).
Name with Special Characters: Accented characters (é, ñ, ü) must be UTF-8 encoded throughout the pipeline; failure causes Workday reject records at the SOAP/REST interface.

Cutover

Cutover is executed in a locked maintenance window with Ellucian Colleague Student module set to read-only. A final reconciliation compares source-file row counts against Workday committed records; discrepancies exceeding a 0.1% variance threshold halt cutover and trigger exception review. The migration is reversible: the last three Colleague backups are retained for 30 days post-cutover, and Workday maintains an import log that supports row-level rollback via Delete_Batch API calls if a systemic data corruption is discovered. A delta-load job runs 48 hours after cutover to capture any registrations or financial-aid offers that arrived in Colleague during the snapshot freeze. Full sign-off requires written approval from the Registrar, Student Financial Services, and the Workday Student administrator confirming record counts, balance totals, and enrollment status are accurate in the target system.
