Decommission a validated computerized system at end-of-life. Covers data retention assessment by regulation, data migration validation (mapping, transformation, reconciliation), archival strategy, access revocation, documentation archival, and stakeholder notification. Use when a validated system is being replaced, reaching end-of-life without replacement, vendor support is discontinued, multiple systems are consolidating, or regulatory changes render a system obsolete.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Decommission Validated System

Plan and execute the controlled retirement of a validated computerized system while preserving data integrity and meeting regulatory retention requirements.

## When to Use

- A validated system is being replaced by a new system
- A system is reaching end-of-life with no replacement (business process eliminated)
- Vendor discontinues support for a validated product
- Consolidation of multiple systems into a single platform
- Regulatory or business changes render a system obsolete

## Inputs

- **Required**: System to be decommissioned (name, version, validation status)
- **Required**: Data retention requirements by regulation (21 CFR Part 11, GLP, GCP)
- **Required**: Replacement system (if applicable) and migration scope
- **Optional**: Current validation documentation package
- **Optional**: Data volume and format inventory
- **Optional**: Business owner and stakeholder list

## Procedure

### Step 1: Assess Data Retention Requirements

Determine how long data must be retained and in what form:

```markdown
# Data Retention Assessment
## Document ID: DRA-[SYS]-[YYYY]-[NNN]

### Regulatory Retention Requirements

How to install

The exact contents, by fingerprint
mdr add pjt222/agent-almanac/decommission-validated-system@sha256:a864f4f08fab41e5

The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
