A dated cutover, formal retirement statement or material later implementation milestone.
Evidence boundary: The evidence supports a completed phased rollout to Dynamics 365 for the named operational functions. It does not identify the predecessor product or prove retirement of every legacy integration.

Programme context

Weetabix deployed Dynamics 365 Finance and Supply Chain Management to unify finance, manufacturing, supply-chain and production-planning processes previously supported by a fragmented customised on-premises ERP environment.

Why this matters: This record identifies a named organisation, a source and destination platform, an affected workload and an evidence-bounded operational stage.

Implementation and architecture

  • Microsoft FastTrack and implementation partner HSO supported the migration.
  • The target platform unifies finance, supply chain and production planning.
  • Handheld production-device integration and reported outcome metrics remain attributed customer/vendor claims.

Known unknowns and contradictions

  • The product name and version of the predecessor ERP.
  • The exact calendar go-live date.
  • The complete list of retired customisations and integrations.

No missing fact is inferred to broaden the source-supported migration claim.

PlatformTrace analysis

The evidence supports a completed phased rollout to Dynamics 365 for the named operational functions. It does not identify the predecessor product or prove retirement of every legacy integration.

Performance, cost, uptime and operational outcomes remain attributed source claims unless independently stated otherwise.
