Upgrade¶
Safe Upgrade Pattern¶
- build and validate the new project version first
- keep the current deployment available
- deploy into a versioned root
- restart in the intended mode
- verify with status, HMI, and one safe process proof
- keep rollback ready until the upgrade is accepted
Rollback Rule¶
If the new version is not clearly healthy, roll back quickly:
Before You Upgrade¶
- read Version History
- read Changelog
