Summary

In this chapter, we explained the options that are available for planning a migration from Skype for Business on-premises, and Skype for Business Online to Microsoft Teams. You learned that in order to upgrade to Teams from Skype for Business on-premises, you need to configure hybrid connectivity to Microsoft Teams before choosing and configuring the appropriate coexistence mode. Additionally, we showed you how an upgrade to Teams from Skype for Business Online only requires coexistence settings to be configured.

We also explained how coexistence may be configured at both the organizational and per-user level, and how users' existing meetings may be migrated either automatically or triggered manually with PowerShell commands. Finally, we demonstrated how to configure Teams upgrade notifications and how to set your default apps while in coexistence mode.

In the next chapter, we will demonstrate how to assess your network readiness for a Microsoft Teams deployment. You will learn how to use the Teams Network planning tool, and the Network Testing Companion tool within the Teams admin center. We will also show you how to calculate the bandwidth you will require to successfully run Teams Meetings and Live Events, how the required network ports and protocols need to be configured, and how to optimize media configuration using Quality of Service (QoS).
