Hi, what have you done after the migration from Skype onPrem to Teams.If your Hosting provider ist still srv: , this means your user is still on the SFB onPrem server.The msRTCsip-Deploymentlocator should be sipfed.online.lync.com for all user in your AD

We didn't had much meeting data or contact list to migrate from skype to teams.So we basically shutdown the skype server.Changed dns entry and changed the coexistence mode to teamsonly in teams admin center.

  I tried running powershell command
  Grant-CsTeamsUpgradePolicy for the users but it failed saying I have to run Move-CsUser first.
  But when I tried executing Move-CsUser command, I get error saying Move-CsUser is not recognised .

    You can test with one user to change the msRTCSIP-DeploymentLocator from SRV: to sipfed.online.lync.com, wait for AAD Sync and check the Interpretedusertype. If this is ok for the user, clear the msRTCSIP-DeploymentLocator and check the Interpretedusertype after AAD Sync.
    
    This is for all users:
    Get-ADUser -Filter {UserPrincipalName -eq "UPN"} -Properties * | Set-ADUser -clear msRTCSIP-DeploymentLocator
    
    Here is a good lin, how to remove the SfB onPrem correct with all steps
