If your organization is ready to upgrade to Teams, take time to communicate to users to let them know what's happening and allow them to acclimate to Teams. This will help ensure they have a positive upgrade experience and help alleviate calls to your helpdesk. For sample communication templates, download our Upgrade Success Kit.

Do I upgrade all users on my tenant together, or can I opt to upgrade select users at a time?

You have the flexibility to upgrade users to Teams as it makes sense for you, whether it's individuals, groups of users, or your entire organization. To help understand the optimal approach for your organization, review the various coexistence and upgrade modes you can enable.

What happens after my users are upgraded?

After your users are upgraded to Teams (Teams Only mode):

  • Their Skype for Business client will be disabled for use as all chat and calls will go to Teams. This client will continue to be used for previously scheduled Skype for Business meetings. If this desktop client is uninstalled, users will be redirected to access previously scheduled Skype for Business meetings via the Skype for Business web app.

  • Any Skype for Business meetings scheduled before the upgrade will work as designed, but all new meetings will be scheduled in Teams. If users attempt to sign-in to Skype for Business, they'll get a notification from their client that they've been upgraded to Teams. Users will need to manually uninstall the Skype for Business client on their mobile device.

Will users still be able to use Skype for Business after I activate the upgrade notification in their client?

Yes, the upgrade notification will simply alert users that Skype for Business will be upgrading to Teams and invite them to get started with Teams if they haven't already. We recommend complementing this notification with an awareness campaign (emails, FAQs, helpdesk readiness, posters/signage) to communicate further details specific to your organization, such as timing for the upgrade, calls-to-action for the user, access to training, and so on. For communication templates, download our Upgrade Success Kit.

What does this mean from a licensing perspective? How will customers pay for capabilities such as Audio Conferencing and calling in Teams?

Teams is available in Microsoft 365 and Office 365 suites. Capabilities that are premium workloads in Skype for Business Online today will continue to be premium workloads in Teams. Existing licensing investments made by customers carry forward to Teams. For example, if a customer has purchased Audio Conferencing standalone or as part of E5 with Skype for Business, Audio Conferencing will be enabled in Teams as it's available today.

What are the benefits of Teams' back-end infrastructure?

Teams is built for the cloud on a highly scalable microservices architecture that's efficient in bandwidth consumption, provides more robust telemetry, and enables maintenance and upgrades with minimal disruption. As a result, users see faster meeting join times and a better browser experience without needing to download plug-ins. This modern infrastructure makes it easy to tap into Microsoft Cognitive Services—which include transcription, translation, speech recognition, and machine learning capabilities—and have the power to make communication and collaboration easier and more effective.

Are third-party audio conferencing providers (ACP) supported in Teams?

There are no plans to support third-party audio conferencing providers (ACP) in Teams.

Meetings scheduled in Teams will need to utilize the Audio Conferencing services of Microsoft 365. Support for the integration of third-party party audio conferencing providers (ACP) in Skype for Business Online has been extended to July 31, 2021, with limited support for remaining active tenants to allow additional time for transition.
