Appian Upgrade Clarification

Question

Hi, Appian has now moved to a monthly release cycle starting with version 26.1. Based on version 26.2 is released on 27 February 2026 , and the support expiration date for 26.1 is also 27 February 2026 , I need clarity on whether an upgrade must be performed on the same day to remain fully supported. If a release includes functionality deprecations or removals that require remediation before upgrading, do we have a grace period to complete those changes? Our usual process involves upgrading non‑production environments first, performing thorough testing, and ensuring everything is stable before proceeding with the production upgrade. Given the support end date, do we need to perform upgrade all environments immediately without testing?

No upgrade required on 27 Feb; no immediate all-env push without testing. 
 26.1 support ends 27 Feb (26.2 release), but policy allows flexible timing post-expiration for upgrades. Grace period exists via hotfixes/support while remediating deprecations; follow non-prod -> test -> prod process.
