Configure site collection version and upgrade settings

When Office 365 upgrades become available, the SharePoint Online administrator (also called the global admin) is the first to hear about it. SharePoint Online has a hierarchical structure, so upgrades are delivered in a cascading way. Upgrades start with the top level or tenant level of the hierarchy and then flow down to site collections and sites below.

The SharePoint Online administrator determines who is allowed to upgrade site collections and can restrict upgrade permissions to a select group, or delegate upgrade responsibilities to site collection admins. Each method has its benefits.

Limit upgrade options when you want to arrange a coordinated rollout of new features, or you have highly customized sites that need thorough testing before being upgraded. You can also delegate upgrade tasks when you have numerous site collections within your subscription. If, for example, you have team sites, personal sites, publishing sites, and project sites, delegation spreads the work around and enables site collection admins to determine when the time is right to implement the upgrades for their individual sites.

About site collection versions

One of the best things about SharePoint is the ability to create team sites and other kinds of sites whenever needed. If you're rolling out an upgrade, you don't want it to affect workday tasks or prevent users from creating sites when and where they need them. With versions, you can update your subscription to the new environment but allow your users to continue creating sites that look and feel like the old version. The following scenario is an example of why you might want to do this:

Rob, the SharePoint Online administrator at Contoso just upgraded his subscription at the tenant level but is still working out the plan for upgrading the hundreds of site collections within his tenant. At the same time, the marketing team is preparing to announce some new products and needs to collaborate with partners in various geographical locales who can't wait until the upgrade process is complete so they create a 2010 project site to use until their project completes.

You can choose whether to allow versions in your subscription and decide how users can upgrade their own site collections. Here's an explanation of the version options available in the SharePoint admin center.

Option

Description
