Let me now show you how to adjust your coexistence mode. As you can see here, we're in the Microsoft Teams Admin center. If we wanted to adjust coexistence, we would simply navigate to the left-hand rail for Teams and then go all the way down to Teams upgrade settings.

Here, we can see coexistence mode alongside a drop-down menu. Currently, my coexistence mode is set to islands, but if I wanted to change that, I'll simply click here, and it will give me all of the options. As I mentioned in the previous lecture, we can see all five options: Islands, Skype for business only, Skype for Business with Teams collaboration, Skype for Business with Teams collaboration and meetings, and Teams only. And it gives me a quick description of each of these options.

Now as I was set to island mode, if I wanted to change it to Teams for that upgrade, I can click Teams only and hit 'Save'. Once I do this, it will give me a warning stating that users will no longer be able to use Skype for business except for when joining Skype meetings. All of these users will be Teams only unless an explicit per user upgrade policy is set. If I'm sure about these details and I want to continue with this, I simply understand the change of the effect and hit 'Save'. Once I do that, my cognizance mode is set to Teams only, and I'm good to go.
