When we try to move a user from Skype to Teams we encountered this issue
Move-CsUser -Identity $SFBuser -Target sipfed.online.lync.com -MoveToTeams -Credential $Mycreds -HostedMigrationOverrideUrl $url -Proxypool POOLFEFQDN -DomainController FQDNOFTHEDC -BypassAudioConferencingCheck -Confirm:$false -BypassEnterpriseVoiceCheck
Couple of days ago, we used the same cmdlet, same Front Endserver and the move operations was successful.
Environment
Platform Windows Server 2012 R2 Standard Edition
