Migrate without the horror stories — coexistence until proof, cutover with evidence.

Everyone knows a migration horror story: the cutover weekend that ate the quarter, the history that never arrived, the authorization model that broke on day two. ERP Migration inverts the risk with proof gates — route coverage, mapping completeness, connector maturity, and reconciliation proven before anything switches. The legacy system keeps running until the evidence says otherwise.

## Why migrations fail without proof gates

Most migrations fail at cutover: the mapping looked complete in a spreadsheet, then authorization breaks, history goes missing, and the business discovers the gaps during its busiest week. Proof gates invert the risk — every profile must demonstrate route coverage, mapping completeness, connector maturity, authorization evidence, lineage, conformance, and reconciliation before it ships. Coexistence is the default until the evidence says otherwise.

## Migration gates

- **Route coverage:** Every legacy API route mapped to an XRP equivalent with tests
- **Object mapping:** Invoices, orders, items, vendors mapped to counterparts without loss
- **Authorization evidence:** Access controls verified working after migration, not assumed
- **Reconciliation:** Before/after equality proven on data, balances, and history
- **section:** capabilities

## Who answers for Migration

Four roles, four anxieties, one proof record answering each.

### Section 1

col Title: CEO

col Cont: No horror-story cutover. Coexistence runs until reconciliation proves each domain, so the business never bets a quarter on a weekend.

### Section 2

col Title: CFO

col Cont: Existing licenses and customizations map with verdicts instead of being written off. History migrates with lineage, so audits cross the boundary intact.

### Section 3

col Title: CIO

col Cont: Integrations map with coverage tests and drift control instead of hopeful re-pointing. Each profile releases independently as its gates pass.

### Section 4

col Title: COO

col Cont: Operations never stop for the migration. Domains cut over one by one with fallback positions staged until the new core proves itself under load.

## Profiles by platform

Each profile below follows the same proof-gated pattern — mapped, tested, reconciled, then released. Coexistence runs until the gates pass.

### data View

section: applications

### SAP S/4HANA

Production orders, routings, financial documents, and warehouse tasks mapped with route coverage proven. Custom extensions inventoried with per-object verdicts: adopt natively, wrap compatibly, or rebuild under governance.

### Oracle Fusion

Work orders, process manufacturing, and financials with child-entity events mapped to XRP protobuf and event contracts. Business-event parity verified before any domain cuts over.

### NetSuite and Dynamics

SuiteAnalytics surfaces, Dataverse entities, and workflow automations mapped with readback verification. SaaS-only assumptions get re-examined against customer-deployed reality with the differences documented.

### Acumatica and Infor

SMB-leaning suites and industry clouds mapped with the same rigor: objects, routes, connectors, and history reconciled. Industry-specific extensions keep their behavior under the new core.

## Migration questions

### Section 1

Which platforms have profiles?

SAP, Oracle, NetSuite, Dynamics 365, Acumatica, and Infor follow the same proof-gated pattern, each releasing independently as its gates pass.

### Section 2

What happens to historical data?

History migrates with full traceability — every record carries its source identity and lineage, so audits can follow transactions across the cutover boundary.

### Section 3

How long does coexistence last?

As long as the business needs. The legacy system keeps running while XRP proves each domain, and cutover happens domain by domain as reconciliation gates pass.

### Section 4

We have heavy customizations. Are they lost?

No. Extensions inventory with per-object verdicts — adopt natively, wrap compatibly, or rebuild under governance — each with its own evidence gate before the legacy retires.

### Section 5

How long will this take? Be honest.

Domains cut over as their gates pass, not on a big-bang date. Most estates see first domains live in weeks with the long tail following — and every step is reversible until reconciliation proves it.

value: Each profile releases only after proving real compatibility — route coverage through reconciliation — not a long endpoint list. Your current ERP keeps running in coexistence while XRP proves, maps, and reconciles at the pace your business can absorb.
