GxP SYSTEM DECOMMISSIONING · LEGACY SHUTDOWN

Decommission GxP systems, without losing records, context or auditability.

We plan and execute the controlled retirement of validated legacy systems. Data, metadata, audit trails, retention duties and retrieval remain demonstrably controlled after shutdown.

How is a GxP system decommissioned?

A GxP system is decommissioned through approved change control and a risk-based plan. The team defines scope and owners, inventories regulated records and dependencies, secures retention and retrieval, validates any migration or archive, reconciles the result, revokes access and interfaces, updates the system inventory and approves a final decommissioning report.

01 Controlled retirement

A shutdown is complete only when the evidence remains usable.

Turning off a server or cancelling a licence is a technical action. A compliant retirement also closes process, data, supplier, access and documentation obligations.

02 Decommissioning plan

What belongs in a decommissioning plan?

The plan connects the retirement decision to executable controls. Each row defines what belongs into the plan and which deliverable makes the step auditable.

Plan section What must be documented Deliverable
1. Approved change & scope Reason, systems, processes, records, sites, dates, owners and decision bodies. Decommissioning strategy and approved plan
2. Record & retention matrix Record class, legal basis, retention period, owner, target, access and destruction rule. GxP record, retention and legal-hold matrix
3. Technical dependency plan Interfaces, jobs, identities, certificates, reports, integrations and infrastructure shutdown sequence. Data-flow and dependency inventory
4. Migration & archive protocol Mapping, extraction, transfer, checksums or reconciliation, exception handling and retrieval tests. Migration or archive validation protocol
5. Closure & operating model Residual risks, archive ownership, periodic readability checks, supplier exit, inventory update and final approval. Decommissioning report and inventory update

Every row must be closed before the source system is finally shut down.

03 Archive is not backup

Which data must be archived?

The answer follows the applicable GxP context and retention rule, not a universal file list.

BACKUP

Technical recovery

Supports recovery after failure, restores a last known state so operation can continue.

  • × Kein Aufbewahrungs-Nachweis
  • × Kontext geht bei Rotation verloren
  • × Ersetzt kein GxP-Archiv
ARCHIVE

GxP retention

Preserves final records and context for the required retention period. Readability, integrity and retrieval are demonstrated and validated.

  • ✓ Aufbewahrungspflicht abgedeckt
  • ✓ Metadaten & Kontext erhalten
  • ✓ Abruf getestet & freigegeben
Release criterion The source system is not finally shut down until completeness, integrity, readability and retrieval of the retained records have been demonstrated and the responsible owners have accepted the result.
04 FAQ

Frequently asked questions about GxP system decommissioning.

How is a GxP system decommissioned?

Through approved change control, a risk-based decommissioning plan and documented acceptance criteria. Before shutdown, GxP records, metadata, audit trails, interfaces and retention duties are assessed. Migration or archiving is validated and reconciled. Access removal, technical shutdown, inventory updates and a final report follow.

What belongs in a decommissioning plan?

At minimum: scope, rationale, owners, a record and retention matrix, interfaces, target architecture, migration or archive procedures, test and reconciliation criteria, shutdown sequence, exception handling, residual risks and final approval.

Which data must be archived?

All records and contextual information that must be retained under the applicable GxP framework and retention period. This may include source data, metadata, audit trails, electronic signatures, reports, master data, configurations and validation documents. The specific selection is justified per system.

Is a backup sufficient as a GxP archive?

No. A backup primarily supports technical recovery. An archive must protect final records and metadata from change throughout the retention period and ensure readability, integrity and retrieval. Archive and retrieval procedures must be appropriately validated and tested.

When can the legacy system be shut down permanently?

When the approved acceptance criteria are met: relevant data and metadata are completely migrated or archived, reconciliation has passed, retrieval has been tested, ownership has transferred, interfaces and access are closed in a controlled manner, and the final report is approved.
