ERP Decision Guide
The cloud simplifies infrastructure, but not decision-making. The budget depends primarily on what you keep, what you rebuild, what you retire, and the volume of data and integrations that need to be reconstructed.
When an ERP changes versions, data models, or integration logic, you must treat the project as a transformation, not just a hosting move.
Analysis + remediation + migration + integrations + testing + adoption
Proposed working guide: adapt the deliverables, roles and criteria below to your scope and obtain client-side validation. They describe neither a delivered engagement nor a verified product capability. No actual owner, price or schedule is announced.
Proposed deliverable: Inventory of the ERP, customizations, interfaces and data constraints.
Role to designate: Business and architecture owners, to be designated client-side.
Proposed validation: Confirm current-state scope and dependencies to retain before choosing the target.
Proposed deliverable: Target map: processes, functions, interfaces and operating responsibilities.
Role to designate: Business and architecture owners, with client-side validation.
Proposed validation: Distinguish standard functions, add-ons and exclusions; document what must stay and what must change.
Proposed deliverable: Register of data, process and customization gaps, with correction decisions.
Role to designate: Data and process owners, to be designated.
Proposed validation: Validate transformation rules and required corrections before migration trials.
Proposed deliverable: Migration plan and interface contracts: retained data, transformation rules and expected reconciliations.
Role to designate: Proposed data and integration teams, under client-side owner validation.
Proposed validation: Plan reconciliation to source data and an exchange-recovery test; record still-open gaps.
Proposed deliverable: Critical-scenario, exception and control results, with an open-issue register.
Role to designate: Business users and test owners, to be designated.
Proposed validation: Require evidence for selected processes, blocking gaps and correction responsibilities before deciding progression.
Proposed deliverable: Cutover plan, incident responsibilities, restoration procedure and adoption support.
Role to designate: Go-live decision owner and support teams, to be designated.
Proposed validation: Accept residual risks and confirm restoration responsibilities; the restoration test remains to be performed.
Source: existing page criteria and PlanAxion methodology decision frameworks in the ERP Evidence CMS. Detailed roles and validations are proposed methods for approval, not client facts. Depth depends on a technical move, version change or operating-model transformation.
An independent client-side ERP consultant can separate architectural choices, integrator assumptions, and business decisions before the budget is committed.

Not necessarily in the short term. The benefit depends on the level of simplification achieved.
Technically sometimes, but you must distinguish between those that create real value and legacy workarounds.
PlanAxion helps you separate technical migration, integration redesign, data, security, and process changes before estimating migration costs.
