"Move-CsUser : HostedMigration fault" when you move users to Skype for Business Online from an on-premises Microsoft Lync Server

Solution
Before you try to migrate an on-premises Lync user to Skype for Business Online in Microsoft 365, your Microsoft 365 Skype for Business Online organization must be enabled for Shared Session Initiation Protocol (SIP) Address Space.
