Upgrading and patching your instance requires planning, testing, and validation. To ensure a safe and effective upgrade, read the release notes, create upgrade plans, and test your upgrade on non-production instances before upgrading your production instance.

Important: These topics contain in-depth explanations about upgrades. For a step-by-step reference of upgrade steps, refer to the Upgrade planning checklist.
