Legacy ERP Replacement

Retire your legacy ERP without retraining your team from scratch — agents map the old system, port the logic, and prove parity before cutover.

Full-system replacement, not incremental augmentation. This engagement is for teams ready to retire their current ERP entirely. If you want to keep your current ERP and add specific capabilities, see Custom Workflow & Integration Engineering →

When legacy ERP replacement goes wrong

Most replacement projects fail for the same reasons — scope defined too late, business logic lost in transition, teams left to figure out a new system mid-operation.

Business logic lost

Pricing rules, approval chains, and routing logic built up over years exist only in the old system and in people's heads — not documented anywhere.

No parity verification

Teams cut over to the new system before it's proven against real data. Discrepancies surface after the old system is switched off.

Generic training

Finance, production, and warehouse teams all receive the same generic ERP training — not tuned to how each team actually works.

Scope creep mid-project

ERP replacement scope expands as new requirements emerge — budget and timeline slip, morale collapses, and the project gets abandoned.

No rollback plan

Cutover happens without a defined rollback procedure — when something breaks post-go-live, there's no safe path back.

18-month timelines

Traditional ERP replacement engagements quote 18–24 months and several crore — far beyond what most manufacturers can absorb.

What's included

A structured replacement that addresses each failure mode above.

Legacy system audit

A structured audit of your existing ERP — modules in use, customizations made, integrations active, and user workflows — identifying what must be replicated, simplified, or dropped.

Business logic mapping

Agent-assisted mapping of business logic from the old system: pricing rules, approval chains, production routing, and report definitions — documented before any cutover begins.

Parallel environment

FactoStack runs alongside the legacy system on real data, with defined parity checkpoints across the modules being replaced — no forced cutover until parity is proven.

Data migration

Migration of master records (items, customers, vendors, BOMs) and relevant historical transactions with reconciliation against the source system.

Role-specific onboarding

Your production staff, warehouse team, and finance team each get onboarding built around how they worked in the old system — not a generic training deck.

Cutover plan

A defined go/no-go checklist, rollback procedure, and post-go-live support window — so cutover is a planned event, not a forced switch.

Who this is for

Aging SAP / Zoho / Odoo

Multi-plant groups with ₹25Cr+ revenue on SAP Business One, Zoho ERP, Odoo, or a heavily customized legacy system that no longer fits how the business operates.

End-of-support systems

Organizations where the vendor has discontinued support, where customizations are blocking upgrades, or where the annual maintenance cost has exceeded the value delivered.

Cost-conscious enterprise

Businesses told legacy ERP replacement will take 18–24 months and cost several crore — and wanting a faster path for manufacturing-specific operations.
