The Salesforce Spring '23 release is coming soon. Use your sandbox to get early access to new features and test your configurations before the production upgrade. Here's how:

The Spring '23 sandbox preview window is scheduled to begin January 6, 2023. You must have an active sandbox on a preview instance before January 5, 2023 to take advantage of the Spring '23 preview. In most cases, you don't need to do anything because your sandbox is already on a preview instance.

Read the Spring '23 Sandbox Preview Instructions and use the Sandbox Preview Guide to see whether to take action. The Sandbox Preview Guide simplifies how you plan if and when you need to trigger a refresh for your existing Sandbox orgs. Type in your Sandbox instance (CSx) to get started.
