Seasonal releases, sandbox preview and release updates

How to de-risk the three seasonal releases: plan backward from published upgrade dates, place sandboxes on preview or non-preview instances around the cutoff (Release Type, Request Non-Preview, clones), handle package uploads during the preview window, test release updates before sandbox test periods end, and turn release notes into communication and phased rollout.

Official exam objective
Given a customer scenario involving a new Salesforce release (Summer, Winter, Spring), recommend the appropriate strategy to mitigate risks.

What the exam expects

  • Build a release readiness plan that works backward from the published sandbox and production upgrade dates, with regression testing on a preview sandbox.
  • Decide whether each sandbox should be on a preview or non-preview instance, and what to do before or after the cutoff: refresh, Request Non-Preview, or clone.
  • Predict which orgs can install a package uploaded during the preview window.
  • Schedule release update test runs so sandbox testing finishes before its test period ends.
  • Use release notes Feature Impact filters, super users and phased rollout to communicate changes.

Key terms: preview instance (sandboxes here get the next release several weeks before production; Help says 6 weeks, Trailhead says 4-6); non-preview instance (sandboxes here stay on the current release until production upgrades); cutoff date (the last moment a create or refresh can land on a preview instance); Release Type (the Sandboxes page column showing preview or non-preview); release update (a Salesforce change to existing behaviour with a Complete Steps By date and an optional test run).
