Move selected users to Teams...
Skype for Business 2015 Cumulative Update number 8 will be released around the same time as SfB 2019. This version will also have the "move to Teams" option in the Control Panel and users can then be moved back and forth between Teams and on-prem Skype for business. When a user is "moved to Teams" the Control Panel will show "homed in Teams" versus "SfBO" - this will fixed in a future Cumulative Update for Skype for business 2019. If a user starts the Skype for business client after the user is moved to Teams, a message will say "Your organization is now using Microsoft Teams!" and there will be a button to launch Teams instead. This client experience will be the same for Windows and Mac clients.
Skype for business 2019 front-end servers will require 64GB of memory and this is done for "Future proofing" reasons, there is no architectural change that really require this change. There is also 40% less CPU load compared with Skype for business 2015. A 2019 front-end pool can contain up to 16 front-ends and support 106,000 users.
