The document discusses different hybrid deployment modes for Skype for Business and Microsoft Teams. It describes Islands mode which allows Teams to be used for collaboration while Skype for Business is still used for meetings and calls. It also discusses moving from Islands mode to having Teams handle all unified communications by migrating users and features over time.
