Recently, we have seen questions coming in from Partners about the site collection upgrade experience for their customers who have been upgraded to the new SharePoint Online.
After Office 365 (and SharePoint Online) are upgraded to the new version, end users should not notice a difference with their site collections. They will continue to look and function as they did before.
However, if the Site Collection Administrator pokes around in Site Actions –> Site Settings, they may stumble across the “Site collection upgrade” option, and then hit the following error:
This is due to a setting that can only be changed by the SharePoint Online (or Global) Administrator.
After your Office 365 subscription has been upgraded, for a limited time you can give users a choice between creating site collections by using the SharePoint 2010 look-and-feel, or by using the new SharePoint 2013 experience.
Depending on the setting you choose, you can also control whether or not SharePoint Online site collections created with an earlier version of the templates can be upgraded to the current versions. For example, if you want to temporarily prevent users from upgrading sites while you update any customizations you’ve previously made to a SharePoint Online template, you can configure these settings to prevent the upgrade of any existing sites that use this template.

You can watch a short video of this upgrade process here:
After enabling the upgrade, from the SharePoint Online admin center, you can select multiple site collections, and send Upgrade notifications (with instructions) to Site Collection Administrators.
You can also view the Site collection upgrade settings, looking at the current experience version (2010 or 2013), get the link to the demo site (if the site collection administrator has created one), and enable/disable upgrade on a site-by-site basis.

In Part 2, I’ll post a video by Partner Solution Consultant Jon Horner that goes into detail on what to expect before, during, and after the upgrade; and how to upgrade My Sites to SkyDrive and Team Sites to the 2013 experience.
Very good. Tks
After gone through your article it is easy to understand because you posted screenshots with explanation.
