Case Study

Large Scale Hci Migration Multisite

An anonymized, partner-led delivery program summary focusing on evidence packs, acceptance gates, and operational handover.

Program context (partner-led)

This case study is presented in a partner-led program context. Customer names are not used. The partner retained governance, change control, and final acceptance authority.

Constraints & scale

  • Regulated delivery expectations: evidence packs, rollback discipline, acceptance gates
  • Multi-domain dependencies (platform + network + security + operations)
  • Tight cutover windows with stabilization requirements

What Onsure delivered

  • Scoped engineering execution under partner governance
  • Validation artifacts and as-built documentation
  • Operational readiness handover: SOPs, runbooks, and knowledge transfer

Validation & evidence

  • Implementation evidence captured per acceptance gates
  • Post-change verification with documented outcomes
  • Stabilization checklist completion and handover sign-off

Artifacts handed over

  • As-built diagrams and configuration deltas
  • SOP/runbook pack aligned to day-2 operations
  • Validation report and acceptance checklist

If you are delivering a similar program, we can align on scope intake and evidence expectations.

Artifacts Handed Over

Delivery is considered complete only when agreed artifacts are validated, reviewed, and accepted by the partner.

Risk & Validation Discipline
  • Rollback plans for every change set (or a documented exception).
  • Parallel runs / phased cutovers where risk warrants it.
  • Acceptance gates with evidence: configuration snapshots, logs, test outputs, and as-built deltas.
  • Partner governance alignment: CAB windows, approvals, and sign-offs.
  • Operational readiness: monitoring, runbooks, escalation paths, and KT.
