Steps

Segment your device fleet into cohorts using tags or group identifiers in your fleet management platform; designate a small cohort (canary group) of representative devices for initial rollout
Deploy the new firmware version exclusively to the canary cohort; configure a phased or percentage-based rollout if the platform supports it (e.g., Memfault rollout percentage, Golioth cohort deployment)
Define success criteria and observability hooks before releasing: crash-free rate, successful boot confirmation rate, key metric thresholds (battery life, connectivity uptime); instrument these in your firmware before the OTA
Monitor the canary cohort for a defined soak period (hours to days depending on device duty cycle); use fleet dashboards to compare crash rates and metrics between canary and control cohorts
If success criteria are met, promote the release to progressively larger cohorts (e.g., 10%, 50%, 100%); if regressions appear, halt the rollout and investigate using coredumps or device logs from the canary devices
After full deployment, archive the old firmware artifact and update internal documentation; confirm rollback images remain accessible on devices for emergency revert

Known gotchas

Canary devices should be representative of the real fleet in terms of hardware revision, connectivity type, and firmware history; a canary group of only lab devices will miss field-specific failure modes
Automatic rollback (e.g., MCUboot revert on failed confirmation) is device-side only; fleet-level rollback (re-deploying an older release to the entire fleet) must be done manually through the fleet management platform
OTA updates that change NVS/flash layout or device configuration schema can cause boot failures even when the new image is valid; test migration paths separately from functional changes
