Summary: Learn how site collection administrators can preview a copy of their sites in SharePoint 2013 mode, and then upgrade their sites.

After a server farm administrator has upgraded the databases, site collection administrators can upgrade individual site collections. When site collection administrators first browse to their sites after the database has been upgraded, a notification bar at the top of the site indicates that their sites can be upgraded. The choices are to Start now or Remind me later. Start now begins the site collection upgrade process.

To upgrade a site collection, site collection administrators complete the following steps:

Run the site collection health checks to verify the site is ready to upgrade. For more information, see Exécuter les vérifications au niveau de la collection de sites dans SharePoint 2013.
Create an upgrade evaluation site to preview the differences between versions. (Optional)
Upgrade the site collection.
Verify that upgrade was successful and the site works as expected. For more information, see Examiner les collections de sites mises à niveau vers SharePoint 2013.

This article discusses the second and third steps, and includes procedures for performing these tasks from Site Settings. For information about using Microsoft PowerShell cmdlets to upgrade sites from the command line, see Gérer les mises à niveau de collections de sites vers SharePoint 2013.

Upgrade step 2: Request evaluation site collection and Step 3: Upgrade the site

Important

If you upgrade from SharePoint Server 2010 to SharePoint 2013, there are special considerations for My Sites. (My Sites are not available in SharePoint Foundation 2013.) Make sure that you upgrade the My Site Host site collection before you allow users to access their individual My Sites in SharePoint 2013. This makes sure that the server software and database changes are complete so that users can upgrade their individual My Sites successfully.
A user can upgrade his or her My Site by following the steps to upgrade a site collection later in this article, or a farm administrator can upgrade My Sites by using PowerShell.

Create an upgrade evaluation site (Optional)

As a site collection administrator, you can request a preview of your site collection; this is called an upgrade evaluation site collection. An upgrade evaluation site collection enables you to see your site’s content in a new, separate copy of the site that is running on the SharePoint 2013. Unlike visual upgrade in SharePoint Server 2010, the upgrade evaluation site collection is a complete copy of the site collection, separate from the original. Actions that you take in the upgrade evaluation do not affect the original site.

When you request an evaluation site collection, the request is added to a Timer job (named "Create Upgrade Evaluation Site Collections") which runs once a day. You will receive an e-mail message when the upgrade evaluation site is available. This might take up to 24 hours. The message includes a link to the evaluation site. Upgrade evaluation site collections are set to automatically expire (after 30 days by default). If yours expires before you have finished evaluating the changes, you can request another upgrade evaluation site collection.

To request an upgrade evaluation site collection

Verify that the user account that performs this procedure is a site collection administrator.
On the Site Settings page for the site collection, in the Site Collection Administration section, click Site collection upgrade.
On the Step up to SharePoint 2013 page, click Try a demo upgrade.

This option starts the process of generating an upgrade evaluation site collection.
In the Create Upgrade Evaluation Site Collection box, click Create Upgrade Evaluation Site Collection.

A box opens and informs you that a demo site request was received.
Click Close to close the box.

You will receive an e-mail message when the upgrade evaluation is available. The e-mail message will contain a link to the site collection. Review the site and confirm that your site collection will look and behave as expected in the new user interface.

After you have reviewed the upgrade evaluation and made any necessary changes in your original site based on your evaluation, you can upgrade your site collection.

Farm administrators can use PowerShell to request an upgrade evaluation site collection. For more information, see Gérer les mises à niveau de collections de sites vers SharePoint 2013.
