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

Problem

In a Lync hybrid deployment, when you try to move users from the on-premises server that is running Lync to Skype for Business Online (formerly Lync Online) in Office 365, you receive the following error message in Skype for Business Online PowerShell:

Move-CsUser : HostedMigration fault: Error=(510), Description=(This user's tenant is not enabled for shared sip address space.)

Solution

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