Legacy Dynamics — AX, GP, SL, NAV

Legacy Dynamics Support: AX, GP, SL & NAV

Plenty of businesses still run important work on Dynamics AX, Great Plains, Solomon, or Navision — and run it well. The challenge is rarely just support. It is the widening gap between what the business needs next and what the current platform, team capacity, and roadmap can comfortably absorb. Kendra holds both sides: keep it steady now, and build a defensible path to what comes next.

The Legacy ERP Modernization Review is a fixed-scope Phase 0 engagement, indicative range $3,500–$8,000, confirmed after scope alignment.

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

Support the environment you have, properly, before deciding anything.

Most legacy environments are not failing. They are under-owned. Backlog accumulates, knowledge concentrates in one or two people, and every small friction point becomes permanent because nobody has capacity to fix causes. That is a solvable problem, and solving it is what makes the modernization decision honest.

Legacy ERP support

Ongoing support for AX, GP, SL, and NAV environments where finance and operations still depend on the current system every day.

Operational stabilization

Issue resolution, cleaner ownership, and steadier execution so teams spend less time reacting to recurring friction.

Backlog reduction

Practical cleanup of long-delayed fixes, enhancements, and workflow pain points that have been sitting in maintenance mode.

Workflow improvement

Targeted refinements around reporting, approvals, handoffs, and recurring finance and operations processes inside the current environment.

Business-critical custom apps

Support for proprietary applications and long-running internal workflows that still serve the business well and should not be forced into a replacement agenda.

Automation along the way

Practical automation and AI use cases that improve current workflows while the longer-term modernization plan takes shape.

Modernization decisions are operating decisions, not feature comparisons.

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. The purpose of a review is not to force a platform — it is to make the trade-offs explicit before implementation momentum narrows the decision.

What the evaluation weighs

  • Fit-to-standard and industry depth against how the business actually operates.
  • Extensibility, integration, and the realistic cost of the custom footprint.
  • Data, analytics, and AI-readiness of each option.
  • Security, compliance, and control implications.
  • Total cost and time-to-value, not licence price alone.
  • Change impact and whether the business has the capacity to absorb it.

What the review protects

  • Capital discipline before implementation spend or vendor momentum narrows the decision.
  • Decision-grade scorecards that separate real platform fit from presentation quality and partner bias.
  • TCO, ROI, risk, and change impact rolled into a single recommendation package.
  • Governance, risk logs, and decision controls before the programme accelerates.
  • A clear connection between process design, operating model, and platform strategy.
  • Roadmap clarity on what to stabilize, integrate, extend, replace, or phase.
Dynamics path

Evaluate D365 Finance & Operations, Business Central, CE, Power Platform, and Microsoft-native integration against process fit and change impact.

Alternative platforms

Compare other ecosystems where economics, capability depth, or operating model fit justify looking beyond Microsoft.

Retain and extend

Decide where legacy ERP, custom applications, or specialized systems should be retained, wrapped, integrated, or modernized in stages.

From valuable legacy systems to a unified, AI-ready operating model.

The path is not forced conversion. It is a controlled progression that preserves what works, connects what matters, and creates a governed operating layer across the business estate.

The controlled progression

1Preserve. Keep the AX, GP, SL, and NAV environments that still run critical work running well.
2Respect custom systems. Proprietary applications and long-running workflows often encode how the business differentiates. They are not automatically migration candidates.
3Build the integration fabric. Connect systems through stable interfaces, APIs, workflows, or staged integration patterns.
4Ground the data. Align identifiers, master data, metadata, and business context so reporting and AI work from trusted facts.
5Apply governed automation. Introduce automation where controls, approvals, logging, and operating boundaries are clear.
6Modernize in stages. Move to Business Central, Finance & Operations, or a cleaner mixed-state model on a timeline the business can actually absorb.

The Legacy ERP Modernization Review.

A fixed-scope Phase 0 engagement for organizations that need support now and a sequenced path to what comes next. It produces a board-ready decision package: current-state reality, support risk, process fit, modernization options, TCO and ROI logic, governance considerations, and a roadmap that respects business capacity.

What legacy Dynamics owners ask.

Do we have to migrate off AX, GP, SL, or NAV?
Not on anyone else's schedule. The first decision is what to preserve, what to connect, what to modernize, and where automation can safely improve how work gets done today. Plenty of legacy environments still serve the business well and the right answer is to support them properly while the roadmap takes shape.
Can you support the current environment and plan the move at the same time?
That is the intended model. Stabilization and roadmap planning run in parallel, because deciding a platform while the current environment is unstable produces worse decisions and weaker negotiating position.
What about our custom applications?
They are assessed on their merits, not assumed to be migration candidates. Some proprietary applications represent years of operating knowledge and process design. The question is whether each should be preserved, modernized, wrapped with integration, or connected into a unified landscape alongside Dynamics.
How long does the modernization review take?
The Phase 0 review runs across a typical 8 to 12 week window covering six core decision workstreams, and concludes with a single consolidated decision package for board or executive review.
What happens if the review concludes we should not move yet?
That is a legitimate and reasonably common outcome. A defensible decision to stay, with a documented stabilization plan and a trigger list for revisiting, is more valuable than a migration started because the vendor calendar said so.
Is the review tied to a particular platform recommendation?
No. The framework evaluates the Dynamics path, alternative platforms, and retain-and-extend options against the same weighted criteria. The point is to make trade-offs explicit across fit, risk, economics, change impact, and time-to-value.

Need a clearer path forward for AX, GP, SL, or NAV?

Start with a focused review that clarifies what to stabilize now, what to connect, what to modernize next, and what to leave alone because it still serves the business well.
