Legacy ERP Modernization Review

Modernize without forcing what already works.

A Kendra Dynamics Phase 0 review for organizations running Dynamics GP, SL, AX, NAV/Navision, Business Central, Finance & Operations, CE, and business-critical custom applications. We help leaders stabilize the current state, evaluate practical options, and create a defensible modernization roadmap before implementation momentum takes over.

Indicative fixed-scope review range: $3,500-$8,000, confirmed after scope alignment.

Designed for mixed Dynamics estates where legacy platforms, custom systems, modern ERP, and AI expectations need to be sequenced rather than forced into a single big-bang answer.

Decision clarity before modernization spend accelerates.

Many organizations do not need panic migration messaging. They need a disciplined view of what to stabilize, what to connect, what to modernize, and what to leave alone because it still serves the business well.

This review gives CIOs, CFOs, controllers, and operations leaders a practical decision package: current-state reality, support risk, process fit, modernization options, TCO/ROI logic, governance considerations, and a sequenced roadmap that respects business capacity.

What the review protects

  • 01Capital discipline before implementation spend, vendor momentum, or sunk-cost pressure narrows the decision.
  • 02Decision-grade scorecards that separate real platform fit from presentation quality and partner bias.
  • 03TCO, ROI, risk, and change impact rolled into a single recommendation package.
  • 04Governance, risk logs, steering inputs, and decision controls before the program accelerates.
  • 05A clear connection between business process design, operating model choices, and platform strategy.
  • 06Roadmap clarity for what should be stabilized, integrated, extended, replaced, or phased.

A six-step methodology built for modernization decisions.

The method is designed to reduce selection and modernization risk before the business commits to a platform move, implementation partner, or major budget cycle.

From discovery to recommendation

1

Discovery & current-state

Understand platforms, customizations, process pain, support load, business constraints, and executive goals.

2

Process mapping & capability model

Map finance, operations, CRM, custom app, data, and integration requirements to the future-state operating model.

3

Requirements & RFP pack

Translate business needs into requirements, demo scripts, vendor questions, and evaluation logic.

4

Longlist / shortlist

Compare feasible paths across D365, Business Central, CE, integration, custom app modernization, and retain/evolve options.

5

Demos & scorecards

Use scripted scenarios and weighted scoring to surface platform fit, gaps, risk, and delivery complexity.

6

Business case, roadmap, decision package

Create the recommendation, TCO/ROI model, risk register, and sequenced modernization path.

Modernization decisions are operating decisions, not feature comparisons.

These anonymized patterns show the kind of decision work the review is designed to support: operating context, strategic risk, platform trade-offs, and a value case leadership can defend.

Discrete Manufacturing$800M

Global Supply Chain Consolidation

Fragmented AS/400 and local workflows created supply chain blind spots, inconsistent master data, and planning friction across a global plant network.

  • Weighted D365, SAP, and Oracle comparison
  • Global template and plant rollout logic
  • Approximately 20% lower 5-year TCO model versus SAP
Medical Device$350M

Post-M&A Compliance & Quality

Acquisition growth left regulated quality, traceability, electronic records, and audit readiness spread across multiple systems.

  • Compliance-weighted requirements
  • Risk register and validation scope lens
  • Projected 30% lower audit-prep effort
Professional Services$1.2B

Quote-to-Cash & ASC 606

Disconnected PSA, CRM, HR, and finance created revenue leakage, weak margin visibility, and manual close pressure.

  • Quote-to-cash process and control model
  • D365, SAP, Oracle, NetSuite comparison
  • Approximately $2.5M five-year savings model
Consumer Distribution$500M

Omnichannel Fulfillment

An aging ERP could not sustain peak transaction volume, API needs, real-time availability, or modern WMS expectations.

  • Peak-day demo scenarios
  • API-first architecture review
  • Targeted 15% order-to-cash improvement
Business Services$950M

Multi-Entity Finance & Shared Services

Regional ledgers and reporting definitions slowed consolidation, cash visibility, and shared-services governance.

  • Record-to-report and P2P governance review
  • Multi-entity finance scoring model
  • Shared-services operating leverage roadmap
Custom SystemsMixed Estate

Critical App Continuity

Long-running custom applications still carried business-specific workflow logic that leadership did not want to lose in a modernization program.

  • Retain, wrap, integrate, or modernize decisions
  • Data grounding and API path
  • AI-ready landscape without forced replacement

Weighted scoring for executive trade-off decisions.

The purpose is not to force a platform. The purpose is to make trade-offs explicit across fit, risk, economics, change impact, and time-to-value.
