In the Upgrade Center, you can read about the available upgrades, view screenshots and videos, and link to additional documentation. The Upgrade Center also lists the prerequisites of the upgrade, the permissions required to perform the upgrade, and configuration steps you need to take after the upgrade. Recent upgrades can be easily undone, with one click. If you see an upgrade you are interested in, but are not ready to perform today, you can mark it as "save for later" or get feedback from colleagues by sharing a link to the upgrade by e-mail.
The Upgrade Center does NOT allow you to perform upgrades that you have not been granted permission to perform. Although any administrative user can access the Upgrade Center page itself, each individual upgrade is governed by the appropriate system permissions. If you do not have the appropriate permission, you can view information about an upgrade, but you cannot use it to enable the feature.
The Upgrade Center is a universal feature of the Admin Center and is available in both versions of the Admin Center. In OneAdmin, select the button in the Upgrade Center portlet to access the page. In Next Gen Admin, you can use the Release Center tile on the admin home page to scroll through the most important recent upgrades. To access the full Upgrade Center, you can use search, or select See More on the Release Center tile, then go to the Upgrade Center tab.
