Cloud migration: preserve a usable quality record

An organization migrates ten years of eQMS records into a new cloud platform and plans to retire the old service. Users must retrieve historical CAPAs, attachments, approvals, linked changes, and relevant history for ongoing quality work and inspections.

Standard case study record

Scope and decision fields

Read these fields before the detailed worked case. All organizations, identifiers, test outcomes, and decisions are fictional teaching material.

GxP Assessment
The migration preserves retained quality records needed for ongoing work and inspection. Completeness, relationships, signatures, chronology, and retrievability are GxP-relevant.
Change or Issue
Ten years of eQMS records move to a cloud platform before retirement of the legacy service.
Functions Affected
  • Record extraction and loading
  • Attachment and parent-record relationships
  • Identity, signature, and time interpretation
  • Search, retrieval, export, and archive access
Potential Impact
A required quality record may be incomplete, misleading, associated with the wrong parent, or unavailable when needed.
Deviations / Known Issues
Matching record counts conceal mislinked attachments in the fictional execution. The key strategy is corrected and relationship reconciliation is expanded.

Situation and intended use

An organization migrates ten years of eQMS records into a new cloud platform and plans to retire the old service. Users must retrieve historical CAPAs, attachments, approvals, linked changes, and relevant history for ongoing quality work and inspections.

Define the record before transferring it

Inventory record types and relationships. Identify historical states, exceptional records, attachment formats, signatures, user identities, and time representations. Decide which information remains in an archive and how users will retrieve it after the old service ends.

Evidence design

Counts help detect missing records but do not prove content and relationships. Combine population-level checks where feasible with risk-informed detailed review and justified coverage of exceptions. Define reconciliation rules and tolerances before execution; do not invent a convenient tolerance after mismatches appear.

CheckWhat it can reveal
Record counts by type and stateMissing populations or unexpected duplicates
Field and content comparisonsAltered values or truncated text
Relationship checksAttachment or approval associated with wrong parent
Historical retrievalRecords inaccessible under the intended archive workflow
Identity and time interpretationLost approval meaning or misleading chronology
Exception reviewUnsupported formats, orphan records, unresolved failures

Worked outcome — fictional

All main-record counts match. Detailed checks find that several attachments are linked to the wrong CAPA because the migration used a nonunique display number. The team corrects the key strategy and expands reconciliation to the affected relationship population. It does not accept matching counts as sufficient evidence.

Cutover and release

Define source freeze or controlled delta handling, final reconciliation, authorized go/no-go decision, user access, support, and recovery. Test retrieval through the intended post-retirement route before terminating the legacy service. Keep unresolved exceptions visible with their impact and disposition.

Ongoing responsibility

Assign an archive owner. Monitor retrieval issues and format/access changes. A cloud contract does not transfer accountability for understanding and retrieving the organization’s records.

Challenge: Is a PDF export of every CAPA enough?

Worked answer: Only if the approved record and retention assessment supports that representation and retrieval arrangement. Examine attachments, relationships, relevant metadata/history, signatures, and interpretability before deciding.
