Newlife&nbsp;I do go for Exchange first then do Skype on-prem to on-line to Teams&nbsp;We did, our Exchange 1st, our Skype went to the cloud very quickly after (in a week for over 6k users), and now were switching users to MS Teams Only mode.&nbsp;&nbsp;

Teshi80&nbsp;&nbsp;ok but what is the actual process for removing the Lync Server 2013 from on-premise? do you just uninstall?

Hi&nbsp;Teshi80&nbsp;&nbsp;How did you go about decommissioning the on-premise Lync servers?&nbsp;

teshi80 · Answer

Navishkar Sadheo&nbsp;not worrying about that as we're already on the way to MS Teams&nbsp;so Skype On-prem &gt; Hybrid &gt; Teams Only mode&nbsp;that way you then start to provision New users direct to Teams skipping the S4B steps etc.&nbsp;Then in 2021 or earlier we plan to remove all S4B from our environment, as the online is EOL and on-prem wont be in use.&nbsp;Overall goal for us is to get all users to MS Teams.&nbsp;but the answer to the question you asked&nbsp; is https://docs.microsoft.com/en-us/skypeforbusiness/hybrid/cloud-consolidation-disabling-hybrid&nbsp;Tesh&nbsp;
