The complete workday hcm migration checklist used on 30+ Workday-to-Fusion migrations: tenant audit, subscription renewal timing, integration catalogue, data scope, Fusion target setup, security and access, cutover sequencing, compliance and archive, communications and change management.
The difference between a 10–16 week landing and a 9–14 month slip is checklist completeness. Items omitted from the workday hcm migration checklist don't get done quietly — they surface as emergencies in week 12.
After 30+ Workday-to-Fusion migrations, the workday hcm migration checklist that consistently produces a clean landing has 60+ items spread across nine workstreams. Tenant audit and discovery sets the baseline. Subscription and renewal captures the financial-deadline framing. Integration catalogue inventories everything that touches Workday HCM. Data scope decides what migrates, what archives and what retires. Fusion target setup readies the destination. Security and access maps Workday Domain Security Policies and Role-Based Permissions to Fusion HCM data roles. Cutover sequencing schedules the Friday close-out. Compliance and archive handles the regulator-facing posture. Communications and change management keeps the stakeholder set aligned through the program.
Each workstream has a sequenced item list with owner, dependency, target completion week and verification criterion. The workday hcm migration checklist is reviewed weekly with the steering committee — items in red, yellow, green status. Items moving to red drive immediate workstream-lead conversations. The checklist isn't decorative; it's the operational instrument that runs the program. Programs that try to run the migration on calendar invites and slide decks alone, without a hard checklist, routinely discover that 'integration catalogue' was assumed-done by three different teams and actually-done by none.
The most consequential single item on the entire workday hcm migration checklist is the Workday subscription auto-renewal date. Workday subscriptions are typically 3-year commits with auto-renewal if notice isn't filed by a contractually specified deadline (usually 90–180 days pre-renewal). Missing that deadline locks in another year of PEPM at $30–60 (HCM) or $50–90 (with Payroll) — a six- or seven-figure mistake at enterprise scale. Every workday hcm migration checklist starts with the renewal date prominently flagged and the notice-of-non-renewal item sequenced well in advance of the contractual deadline.
Each workstream has 6–10 sequenced items with owner, dependency, target completion week and verification criterion.

When each checklist workstream peaks, who owns it, and what verification ends it.
Tenant audit completed by HRIS lead with the discovery scan output. Subscription renewal review completed by Finance with vendor contract review. Initial integration catalogue draft completed. Risk register published. Steering committee status report issued.
Integration catalogue closed with per-integration migrate/retire/replace decisions. Data scope per module closed. Fusion environment provisioning kicked off. Fusion HCM data role design started. Compliance retention windows mapped per record class.
Workday DSP/RBP inventory completed and mapped to Fusion data roles. SoD review with InfoSec. Fusion data role design signed off. Configuration baseline established on Fusion side. Cutover sequencing draft published.
Workday extracts running per data scope. Fusion HDL loads progressing per module. Integration rebuild on Fusion side or OIC underway per catalogue. Compliance archive infrastructure being stood up in parallel.
Payroll parallel run executing where in scope. Reconciliation packs being signed off. UAT with HRIS, comp, benefits, payroll leads. Audit-response runbook validation against archive. Cutover plan finalized.
Friday close-out cutover. Workday → read-only. Fusion → live for new transactions. Workday non-renewal notice filed. Decommissioning sub-program starts. Post-cutover support team activated. Steering committee close-out review.
The six items that are most commonly omitted — and most often surface as week-12 emergencies.
Workday subscriptions auto-renew if notice isn't filed by a contractual deadline (90–180 days pre-renewal). Missing the deadline locks in another year of PEPM — a six- or seven-figure mistake at enterprise scale.
10–50 bespoke integrations in a typical enterprise tenant. Rebuilding each takes 1–3 weeks. Discovering them in week 10 instead of week 1 blows up the timeline.
Workday DSPs and RBPs don't map 1:1 to Fusion HCM data roles. Discovered late, this forces emergency security cleanup just before UAT.
200–800 active calculated fields per tenant. Triaging them takes weeks — not an exercise to start after extraction is complete.
100–500 custom Workday reports. Critical reports must be rebuilt in OTBI/BI Publisher before cutover. Decisions on which reports survive triage drive the rebuild workload.
Archive infrastructure must be live and verified before Workday subscription cut. Trying to build the archive after Workday is gone is too late — the source data is no longer accessible.
A complete workday hcm migration checklist runs 60+ items across nine workstreams: (1) tenant audit and discovery — Workday tenant version, R1/R2 cycle position, active calculated-field count, custom BP inventory, custom report inventory, Workday Studio integration inventory; (2) subscription and renewal — current PEPM tier, multi-year commit end date, auto-renewal date, contract notice periods; (3) integration catalogue — every inbound and outbound integration, partner systems, EIB schedules; (4) data scope — modules in scope (Core HR, Comp, Benefits, Absence, Talent, Time, Payroll Results), retention windows by record class; (5) Fusion target setup — controlled-release timing, environment provisioning, Fusion HCM data role design; (6) security and access — Workday Domain Security Policy inventory, Fusion data role mapping, ISU provisioning; (7) cutover sequencing — Friday close-out timing, parallel-run scope, decommission timing; (8) compliance and archive — retention policies, audit-response runbooks, GDPR readiness; (9) communications and change management — stakeholder updates, training, post-cutover support. Workday hcm migration checklist completeness is the difference between a smooth landing and emergency war rooms.
Tenant audit. Specifically: pull the current Workday tenant version, confirm R1/R2 release cycle position, run the discovery scan to catalog active calculated fields, custom business processes, custom reports and Workday Studio integrations. Without this baseline, the rest of the workday hcm migration checklist is hypothetical — you cannot size, scope or sequence the migration before you know what's actually in the source tenant. The tenant audit takes 3–5 days with the right tooling, surfaces 200–800 calculated fields, 50–200 custom BPs, 100–500 custom reports and 10–50 Workday Studio integrations in a typical mid-market or enterprise tenant, and produces the customization inventory that drives every downstream estimate.
The Workday subscription renewal date is the most important single item on the workday hcm migration checklist. Workday subscriptions are typically 3-year commits with auto-renewal if notice isn't given by a contractually specified date (usually 90–180 days pre-renewal). Missing that notice deadline locks in another year of PEPM at $30–60 (HCM) or $50–90 (with Payroll) — a six- or seven-figure mistake at enterprise scale. The checklist captures: current subscription end date, auto-renewal date, notice-period deadline, contract escalation clauses, multi-year commit position. The cutover is scheduled to land at least 30 days before the renewal so all transactions have flowed to Fusion before the subscription decision is final, and the notice of non-renewal is filed well in advance of the contractual deadline.
Every inbound and outbound integration touching Workday HCM, with five fields per integration: (1) direction (inbound, outbound, bi-directional); (2) Workday endpoint (REST v40+, SOAP, RaaS, EIB, Workday Studio); (3) partner system (payroll provider, benefits broker, time clock, recruiting platform, learning provider, data warehouse, etc.); (4) frequency (real-time, hourly, daily, weekly, on-demand); (5) business owner. A typical mid-market Workday tenant has 20–50 integrations; an enterprise tenant 100–250. The workday hcm migration checklist requires every integration to be classified as migrate (rebuild on Fusion side), retire (no longer needed under Fusion), or replace (different partner system under Fusion). Migration of integrations is typically the second-largest workstream after data migration itself.
Yes — and the parallel-run scope is one of the most consequential items on the checklist. The decision is binary per module: parallel run yes/no. For Workday Payroll in scope (US/CA/UK/FR), parallel run is mandatory — 1–2 pay cycles minimum. For Workday Time Tracking in scope, parallel run is recommended for one full pay cycle. For Workday Benefits, parallel run is typically skipped (validation is via reconciliation pack rather than live transactions). For Core HR, parallel run is replaced by a defined cutover moment (Friday close-out). For Talent, Learning and Recruiting, parallel run is rarely needed. The workday hcm migration checklist captures the parallel-run decision per module with the rationale and the reconciliation tolerance (typically zero variance on payroll, sub-1% on time).
Workday Studio integrations are bespoke ETL flows authored in Workday's Eclipse-based IDE — they don't migrate to Fusion. The checklist requires each Workday Studio integration to be inventoried with: business purpose, source/destination, transformation logic, error-handling, schedule, owner. Each is then classified as: rebuild in Fusion HCM Integrations (HCM Extracts, REST/SOAP integrations on Fusion side), rebuild in the broader integration platform (OIC, Mulesoft, Boomi, Informatica), or retire. Workday Studio rebuild is one of the most underestimated items on the workday hcm migration checklist — a typical enterprise has 10–50 Workday Studio integrations and rebuilding them takes 1–3 weeks per non-trivial integration. The discovery scan in week one surfaces them; the rebuild planning starts in week three.
Retention windows per record class (IRS W-2 4–7 yr, FLSA 3 yr, ACA 3 yr, ERISA 6 yr, EEOC 3 yr, GDPR HR 6 yr, state UI 4 yr typical), cloud archive backend selection, object-lock policy design, chain-of-custody hash signature pack, audit-response runbook validation (IRS, DOL, EEOC, ERISA, ICO), DSAR runbook validation, GDPR Article 17 erasure workflow, litigation-hold overlays, Privacy Office sign-off, Legal sign-off. Workday hcm migration checklist treats compliance as a parallel workstream that runs from week 1 through cutover — not an afterthought tacked onto the final two weeks.
Decommissioning is the last set of items, sequenced after cutover and parallel-run completion. Step 1: verify cloud archive against source Workday tenant with row-level reconciliation. Step 2: confirm Privacy Office sign-off on archive completeness for GDPR readiness. Step 3: file Workday subscription non-renewal notice with vendor inside contractual notice window. Step 4: switch Workday tenant to read-only mode and notify any remaining users that future lookups go to the archive. Step 5: train HR Ops, Payroll Ops and audit teams on the archive query UI. Step 6: at subscription end date, Workday tenant access ends; archive becomes the sole record. Step 7: file post-decommission audit-response runbook tests with the compliance team to confirm regulator-ready posture. The workday hcm migration checklist treats decommissioning as a 4–6 week sub-program in its own right.
