Stages of the upgrade journey, with emphasis on the Deployment and Implementation stage

This article is part of Deployment and Implementation stage of your upgrade journey. Before proceeding, confirm that you’ve completed the following activities:

Upgrade from Skype for Business Online to Teams

Follow the guidance in this article if you have wholly deployed Skype for Business Online and want to upgrade your users from Skype for Business to Teams. You can upgrade users selectively or all-in, based on the upgrade journey that your organization has chosen, by assigning the appropriate coexistence and upgrade mode to your users.

Important

If you’re an admin on your Office 365 tenant, you may soon start seeing upgrade options in the Microsoft Teams admin center. Having the option to upgrade doesn’t necessarily mean your organization is ready for this change. For the best user experience, confirm that Teams meets your collaboration and communication requirements, make sure that your network is ready to support Teams, and implement your user readiness plan before upgrading users to Teams.

Assign the coexistence and upgrade mode

You can upgrade your users by Teams by assigning the TeamsOnly mode of TeamsUpgradePolicy, which can be performed by using the Microsoft Teams admin center or a Skype for Business remote Windows Powershell session.

For more information, see Setting your coexistence and upgrade settings and TeamsUpgradePolicy: managing migration and coexistence.

Phone System and Teams upgrade

If your Skype for Business Online deployment includes Phone System with Calling Plans and Microsoft is your public switched telephone network (PSTN) provider, upgrading your users to Teams will automatically transition inbound PSTN calling to Teams.

If your Skype for Business Online deployment includes Phone System with Cloud Connector Edition, see the additional considerations for Phone System Direct Routing.
