According to Microsoft, “the duration of each customer’s upgrade will vary by volume of users and characteristics of their deployment, but generally users within a tenant will be upgraded within 24 hours from the start of the upgrade. The assisted upgrade provided by Microsoft will begin in August 2021. This includes: third-party audio conferencing providers (ACP), Skype for Business Online Cloud Connector Edition(CCE), hybrid voice configurations, and Skype Meeting Broadcast.
