The salesforce.com Summer ‘13 release is quickly approaching and soon you'll be able to take advantage of exciting new features and functionality! If you are a Force.com Sandbox customer, you have the opportunity to get early access to Summer ‘13 in your Sandbox and test new customizations and features before your production organization is upgraded.
The Sandbox Preview window for Summer ‘13 is scheduled to begin May 10, 2013. If you would like your Sandbox organization to take part in the Summer ’13 Preview, your Sandbox must be active on a preview instance by May 10th or 11th, 2013 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 a lot of cases, you will not need to do anything, but you may need to take action by May 3, 2013 in order for your Sandbox to take part in the Summer ’13 Preview
What Do I Need to Do?
General Information about Sandbox Refresh: From now until May 3, 2013, all Sandbox refresh requests will be routed to an instance that will be upgraded for the preview. Starting May 4, 2013, all refresh requests will be routed to non-preview instances. We will continue to route refresh requests to non-preview instances until all production instances are upgraded.
Plan for the Sandbox Preview Window: You have from now until May 3, 2013 to decide if you would like your Sandbox to take part in the Summer ‘13 Preview. Follow the steps below for each Sandbox org that you have.
