The salesforce.com Winter '15 release is quickly approaching, and soon you'll be able to take advantage of exciting new features and functionality! If you are a Sandbox customer, you have the opportunity to get early access to Winter ‘15 in your Sandbox and test new customizations and features before your production organization is upgraded.

The Sandbox Preview window for Winter ‘15 is scheduled to begin September 5, 2014. If you would like your Sandbox organization to take part in the Winter ‘15 Preview, your Sandbox must be active on a preview instance by September 5, 2014 to take part in an overall instance upgrade.

Please read carefully and follow the instructions in the next section for specific information on how to handle each of your Sandboxes. In most cases, you will not need to do anything because your Sandbox is already on a preview instance. But you may need to take action by August 29, 2014 in order for your Sandbox to take part in the Winter ‘15 Preview

General Information about the Sandbox Service:

From the time your Production Instance (e.g. NA2, EU1, AP0) was upgraded, all Sandbox creation and refresh requests have been routed to a Sandbox instance that will be upgraded for the preview.  We will continue to route these requests to Preview Sandbox Instances until August 29, 2014.

Starting August 30, 2014, all creation and refresh requests will be routed to non-preview instances until your production instance is upgraded to Winter ‘15.

You have from now until August 29, 2014 to decide if you would like your Sandbox to take part in the Winter ‘15 Preview. Follow the steps below for each Sandbox org that you have.

Note: If you have a full Sandbox, be mindful of the 29-day refresh policy and plan accordingly.

  • If you are refreshing onto a preview instance, do not refresh after you activate the Sandbox on your preview instance.  If you do, you will be refreshed to a non-preview instance.  Between August 29, 2014 and the date in which your production org is upgraded to Winter ‘15, all Sandbox refreshes will be directed to non-preview instances.  We cannot perform a refresh to a preview instance between those dates.
  • If you decide to stay on the current Summer ‘14 release, your Sandbox will not be upgraded to Winter ‘15 until October 18, 2014.

IMPORTANT - Plan Ahead!

The August 29, 2014 deadline is to cut off requests in an attempt to make sure that all preview requests can be met. Due to the number of request, we cannot guarantee that a request to create or refresh before the deadline will result in a sandbox org on a preview instance.

The sandbox copy must complete (pending activation or activated) before the overall instance upgrade starting on September 5. If there are too many requests or if you have a large full sandbox and did not plan ahead, the request you made may not be processed by the time of the upgrade.

If you have a large full sandbox, please keep in mind how much time it takes to complete your Sandbox refresh to ensure your copy is completed by September 5, 2014. If the sandbox copy does not complete by the upgrade on September 5, the copy will be restarted to a sandbox instance that remains on the same version as your production instance. 

Plan Ahead! - You may need to request your refresh in advance of the August 29, 2014 deadline to ensure it completes by September 5, 2014.

Understanding the Preview Window Schedule

In addition to the steps above, use the following graphic to understand what will happen to your Sandbox if you request a new sandbox or refresh an existing sandbox.  For example, if your Sandbox is on CS12 and you refresh it after 12 AM PST on August 30, 2014, it will be moved to a non-preview Instance.
