Upgrade journey diagram, emphasizing Deployment and Implementation

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

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 to TeamsOnly mode by assigning the UpgradeToTeams instance of TeamsUpgradePolicy, which can be performed by using the Microsoft Teams admin center or a Skype for Business remote Windows Powershell session. You can do this either on a per user basis, or on a tenant-wide basis if you want to ugprade the entire tenant in one step.

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

Upgrade all users to Teams at one time

Follow these steps to upgrade all of your users to Teams at one time.

Step 1: Notify the users of the change (optional)

  1. In the Microsoft Teams admin center, select Org-wide settings > Teams upgrade.
  2. Under Coexistence mode, change the Notify Skype for Business users that an upgrade to Teams is available switch to On.

Step 2: Set the coexistence mode to TeamsOnly for the organization

  1. In the Microsoft Teams admin center, select Org-wide settings.
  2. Select Teams Only mode from the Coexistence mode drop-down list.

Upgrade users in stages

Follow these steps if you want to gradually upgrade your users to TeamsOnly.

Step 1: Identify groups of users for upgrade

Often organizations may choose to upgrade their organizations in success waves of users. You'll want to identify these users first so you can easily search for them in the Microsoft Teams admin center. Alternatively, you may want to use PowerShell to more efficiently do this. Once you have identified the set of users for a given upgrade wave, continue with the remaining steps.

Step 2: Set notification for the users in the current ugprade wave (optional)

If using the Microsoft Teams admin center, you can configure TeamsUpgradePolicy for up to 20 user at once:

  1. In the Microsoft Teams admin center, select Users, and find and multi-select the checkbox for up to 20 users who should be upgraded.
  2. Select Edit settings in the upper left corner of the listview.
  3. In the Edit settings pane on the right, under Teams upgrade, change Notify the Skype for Business user switch to On. Note: If the value of coexistence mode is "Use Org-wide settings", you won't see this switch, so you'll need to first explicitly set the Coexistence mode for these users to whatever the default value is for the org.

Alternatively, you may find it easier to enable notifications for groups of users at once using PowerShell.

Step 3: Set the coexistence mode for users to Teams Only

When you are ready to upgrade the users in the current wave to use Teams as their only application, set the Coexistence mode for the users to Teams Only.

If using the Microsoft Teams admin center, you can configure TeamsUpgradePolicy for up to 20 user at once:

  1. In the Microsoft Teams admin center, select Users, and then select the checkbox for up to 20 users.
  2. Select Edit settings in the upper left corner of the listview.
  3. In the Edit settings pane on the right, under Teams upgrade section, set the coexistence mode to Teams Only in the drop-down list.

Alternatively, you may find it easier to upgrade groups of users at once using PowerShell.

Step 4: Repeat steps 1-3 for successive waves of users

As you validate your upgrade to Teams Only mode and are ready to expand, repeat the previous steps to apply TeamsOnly to more users.

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.
