Hi fatshark_2k , I don't know if it is a support way. But if you want to do a cut over migration and you have configured Azure AD sync in the past with a Lync/SfB OnPrem installation, all related attributes are synced to Azure AD. Therefor a cutover is only possible if you disable all OnPrem SfB user for Skype for Business. That way the related SfB attributes will be cleared OnPrem and will be synchronised to Office 365. Afterwards the Office 365 Service will "redeploy" the user accounts with SfB Online aka Teams services. I would suggest testing it in advance.

With the Teams Powershell and a connection to SfB Online you can check the deployment state of a certain user by Get-CsOnlineUser <SIP Address>.
