Rollback Procedures

Model rollback allows rapid reversion to a previous model version when a newly deployed model exhibits degraded performance or errors in production.

Rollback via Lifecycle Manager

# Demote current production model back to staging
request = manager.demote(
    model_id="fraud-detector",
    version="3.2.1",
    user_id="ops@acme.com",
    reason="Accuracy drop detected in production monitoring",
)
 
# Restore previous version to production
request = manager.promote(
    model_id="fraud-detector",
    version="3.1.0",
    user_id="ops@acme.com",
    reason="Restoring previous stable version",
)

Audit Trail

All transitions are logged as LifecycleEvent records:

events = manager.get_events(model_id="fraud-detector", limit=10)
# [LifecycleEvent(event_type="stage_changed", from_stage=PRODUCTION, to_stage=STAGING, ...)]
