🔄 ERP R1 Cutover Analysis

Integration Interdependencies & Business Function Impact

Generated: February 20, 2026 08:23 AM PST

📊 Executive Summary

🎯 Manager Summary: ERP R1 cutover involves 17 integrations across 3 business domains, with 2 critical single-point-of-failure services (COA, FX Rates Hub) and 13 integrations requiring precise go-live day enablement. The cutover window runs April 27 - May 3, with subledger go-live May 4 and GL go-live May 11.

Critical Blockers

COA Service and FX Rates Hub are single points of failure blocking 9 downstream integrations

Go-Live Day Enablements

Temporal/cron schedules must be activated in precise sequence on May 4

Total Integrations

10 RTR, 6 STP, 1 EPM integration spanning 17 repositories

Legacy Deprecations

NetSuite, Xignite, Coupa integrations must be deprecated precisely at go-live

Key Risks & Dependencies

🚨 Critical Risk: COA Service (RTR-INT-002) must complete successfully before Employee Data (STP-INT-020) and Actuals Reporting (RTR-INT-010) can function. This creates a blocking dependency at the start of cutover.

⚠️ Timing Risk: RTR-INT-005 (FX Rates) services have legacy code commented out in production. Deployment MUST occur on May 4 go-live day ONLY, not before. Early deployment causes immediate legacy process failure.

Manager Decision Points

Decision Required	Impact	Deadline	Owner
Approve phased integration deployment strategy (early vs. go-live day)	Determines deployment risk profile and rollback complexity	March 24 (Pre-Cutover Sign-Off)	PMO / Integration Leads
Confirm FX rate source during parallel period (Oracle vs. legacy)	Affects downstream system configuration for Kyriba, NetSuite, Varicent, Anaplan	April 15	Treasury / RTR Team
Approve 3-month overlap period for legacy Currency API	Requires maintaining parallel infrastructure, impacts deprecation timeline	April 20	Engineering / Infrastructure
Sign off on War Room escalation procedures and rollback authority	Defines go/no-go decision process during enablement sequence	April 25	PMO / Tech Leads

Recommended Next Steps

Schedule stakeholder meetings (by March 31) to resolve 5 open questions about FX rates, legacy deprecation timing, and post-go-live NetSuite requirements
Create integration enablement runbook (by April 10) with exact Temporal schedule activation commands, validation checkpoints, and rollback procedures
Conduct UAT mock cutover (Feb 9 - Mar 9) with full integration stack including COA → Workday → Employee Data flow and legacy deprecation simulation
Validate production infrastructure (by April 22): Vault secrets, RBAC entries, OIC connections, Sentry alerts for all 17 integrations
Establish War Room protocol (by May 1) with real-time dashboard, escalation paths, and integration leads on standby for May 4 go-live

Cutover Window: April 27 - May 3, 2026

The ERP R1 cutover involves 17 distinct integrations across Record-to-Report (RTR), Source-to-Pay (STP), and Enterprise Performance Management (EPM) domains. These integrations form complex interdependencies with 9 boundary systems including Workday, Anaplan, Navan, Kyriba, NetSuite, Simple Legal, IronClad, Varicent, and ARCS.

Critical Success Factors:

Chart of Accounts (COA) synchronization must complete before any downstream integrations
FX Rates service acts as a central hub - failure blocks multiple systems
Employee data integration has cascading dependencies on COA availability
Legacy system deprecations must be coordinated with Oracle go-live timing

`RTR-INT-002` COA Service	Oracle ERP availability	Workday, Anaplan, Employee Data, Actuals Reporting	⚠️ HIGH
`RTR-INT-011` FX Rates Hub	Oracle GL availability	Kyriba, NetSuite, Varicent, Anaplan, Currency API	⚠️ HIGH
`STP-INT-020` Employee Data	COA Service, Workday availability	Oracle demographics, expense processing	⚠ MEDIUM
`RTR-INT-010` Actuals to Anaplan	COA Service, Oracle GL data	FP&A reporting in Anaplan	⚠ MEDIUM
`RTR-INT-003` Navan Journals	Oracle AP availability	Travel expense posting to GL	⚠ MEDIUM
`STP-INT-004` Simple Legal	Oracle AP payment processing	Legal vendor payment status	✓ LOW
`STP-INT-019` Supplier Data	Oracle Supplier Hub availability	IronClad supplier records	✓ LOW

🗑️ Legacy System Deprecations

⚠️ Critical Timing Coordination Required: Legacy integrations must be deprecated precisely at go-live. Early deprecation causes business disruption. Late deprecation causes duplicate data and reconciliation issues.

Oracle Integration	Legacy System to Deprecate	Deprecation Action	Timing
`RTR-INT-002` COA to Workday	Workday ↔ NetSuite COA sync	Stop existing COA process in Workday	Subledger Go-Live (May 4)
`RTR-INT-002` COA to Anaplan	NetSuite → Anaplan COA process NetSuite → Anaplan Departments process	Retire old COA and Departments feeds. Keep active until TB close May 7.	Post-TB Close (May 7+)
`RTR-INT-010` Actuals to Anaplan	NetSuite → Anaplan Rev/Expense feeds	Keep in parallel during transition. Deprecate after validation.	Post-GL Go-Live (May 11+)
`RTR-INT-003` Navan Journals	NetSuite ↔ Navan GL update connector	Netsuite stops GL updates to Navan	Subledger Go-Live (May 4)
`RTR-INT-005` FX Rates	NetSuite ↔ Xignite FX integration	Retire Xignite integration (confirmed legacy code commented out)	Go-Live Day (May 4)
`RTR-INT-005` FX to Varicent	Boomi → Varicent FX rates process	Deprecate existing Varicent FX rates in Boomi	Go-Live Day (May 4)
`RTR-INT-011` Currency API	Legacy Currency API (NetSuite-based)	Repoint LA Boomi process to new Currency API. Keep legacy for 3 months.	Deprecate 3 months post-go-live
`STP-INT-004` Simple Legal	Simple Legal ↔ Coupa invoice sync Coupa ↔ Simple Legal payment status	Deprecate both Coupa integrations	Subledger Go-Live (May 4)
`STP-INT-020` Employee Data	NetSuite employee integration (Boomi)	Maintain POST R1 go-live. NetSuite still needs employee data.	No deprecation (retained)

Deprecation Impact Assessment

Open Questions Requiring Resolution:

Q1: Can RTR-INT-005 services be deployed on go-live day (May 4) if NetSuite provides FX rates for May through legacy until cutover?
Q2: When will the Xignite integration be fully deprecated? (Legacy code already commented out)
Q3: Will systems receive FX rates from Oracle (month-end and corporate rates) or continue using legacy rates during parallel period?
Q4: After go-live, is employee data still needed in NetSuite? If yes, how long?
Q5: Will the Salesforce → Anaplan and Greenhouse → Anaplan feeds be impacted by COA changes?

⚠️ Risk Assessment

High-Risk Areas

1. Single Points of Failure

COA Service (RTR-INT-002) and FX Rates Hub (RTR-INT-011) are critical dependencies. If either fails, multiple downstream integrations are blocked, potentially delaying go-live.

Mitigation: Prioritize UAT validation of these services. Ensure rollback plans are tested and documented.

2. Temporal Schedule Enablement Dependencies

13 integrations require cron/Temporal schedule enablement at go-live. If schedules are not enabled or are configured incorrectly, data flows stop immediately.

Mitigation: Create a detailed enablement checklist with validation steps. Conduct dry-run during UAT mock cutover.

3. Legacy Code Commented Out in Production

RTR-INT-005 (FX Rates) and RTR-INT-005 (Anaplan) have legacy logic commented out in code. Deployment must be synchronized with go-live or legacy processes will immediately fail.

Mitigation: Deploy on go-live day only. Coordinate with NetSuite team to ensure legacy processes run through May 3 EOD.

Medium-Risk Areas

Risk	Impact	Mitigation
Trial Balance Close Delay (Apr 7 & May 7)	Blocks COA freeze, data conversion, and reconciliation	Monitor NetSuite close calendar. Escalation plan for delays.
Coupa PO/Invoice Cutoff Enforcement	Late entries cause duplicate POs in both systems	Business communication campaign. System-level enforcement at 12 PM PST Apr 30.
Employee Data Delta Load During PSG US Persons Project	Salesforce may receive events during bulk load	Coordinate with Salesforce stakeholders on delta load impact.
Boundary System API Repointing (Currency API)	Billing, Registrar, and other systems need API changes before go-live	Send communication to impacted teams prior to go-live. 3-month overlap period for legacy API.

Operational Risks

Deployment Timing: All 16 pending integrations must deploy to production within a narrow window. Any deployment failure creates a backlog.
Vault Secrets Management: Production secrets must be created/updated for all services. Missing secrets cause runtime failures.
RBAC and K8s Configuration: Namespace permissions, bucket access, and routing configurations must be in place before deployment.
Sentry Alerts: Monitoring must be configured for all services to detect post-deployment issues quickly.
OIC Connection Configuration: Third-party connections (Simple Legal, IronClad, Golang, R2, NetSuite) must be tested in production environment.

Enablement Timing Estimates

Step	Integration	Estimated Duration	Cumulative Time	Validation Checkpoint
0	Pre-flight Check: Oracle ERP Readiness	30 min	8:30 AM	Infrastructure team confirms all services up
1	Enable COA Service (Workday + Anaplan)	15 min	8:45 AM	COA event published to both systems successfully
2	Enable FX Rates Hub	20 min	9:05 AM	FX rates delivered to all 5 downstream systems
3	Enable Employee Data Stack (3 services)	25 min	9:30 AM	Employee event processed through full pipeline
4	Enable Actuals to Anaplan	15 min	9:45 AM	GL actuals visible in Anaplan workspace
5	Enable Navan Service	10 min	9:55 AM	Test journal posted to Oracle AP
6	Enable Simple Legal + Supplier APIs	15 min	10:10 AM	Payment status update confirmed
7	Execute Legacy Deprecation	20 min	10:30 AM	All legacy crons/schedules confirmed stopped
8	War Room Monitoring & Validation	90 min	12:00 PM	All integrations stable, no errors in Sentry

⚠️ Contingency Plan: If any integration fails validation, the War Room team has authority to either (1) rollback that specific integration while keeping others live, or (2) trigger full rollback to legacy systems. Rollback decision must be made within 30 minutes of failure detection.

✅ Recommendations

1. Implement Phased Deployment Strategy

Phase 1 (Pre-Cutover): Deploy non-critical integrations with schedules in paused state. Validate connectivity and configuration.

Phase 2 (Cutover Window): Deploy critical path integrations (COA, FX Rates) first. Validate before proceeding.

Phase 3 (Go-Live): Enable schedules in dependency order. Monitor each integration before enabling the next.

2. Create Integration Enablement Runbook

Document exact steps for enabling each integration's Temporal/cron schedule, including:

Schedule validation commands
Expected log output for successful startup
Rollback procedures for each service
Smoke test procedures to validate data flow

3. Resolve Open Questions Before Go-Live

Schedule stakeholder meetings to answer:

Xignite deprecation date (NetSuite team)
FX rate source during parallel period (Treasury / RTR team)
Post-go-live NetSuite employee data requirements (HR / STP team)
Anaplan feed impact from COA changes (FP&A team)

4. Conduct Mock Cutover with Full Integration Stack

The UAT mock cutover (Feb 9 - Mar 9) should include:

End-to-end test of COA → Workday → Employee Data flow
FX Rates hub distribution to all downstream systems
Legacy system deprecation simulation (disable NetSuite feeds)
Schedule enablement dry-run with timing measurements

5. Establish War Room During Cutover Window

Create a dedicated Slack/Teams channel with:

Real-time status updates for each integration
Escalation paths for integration failures
Integration leads on standby (Ana Limpo, Priyanka Rawat)
Dashboard showing integration health and data flow metrics
