What is the result of turning off Skype for Business on-prem without migrating all users to Teams considering that these users use Teams in Island Mode?
I know that this is not the supported way of moving from S4B to Teams, but I want to understand the impact of a “migration” done this way.
I looked in the documentation about the upgrade but I only found mention of not having “all the features” of Teams.
In this hypothetical scenario, S4B would be turned off and the DNS changed to Teams.
What happens in that case?
