Brass Contributor

Hi Community


One of the customer has the below things:


Current environment:


Lync 2013
Exchange 2013
UM is currently hosted with Exchange 2013


To move Lync 2013 to Teams
To move Exchange 2013 to Exchange online and use Cloud voice mail.



How to plan this migration?


We know that Lync 2013 to be built as Hybrid with Skype for Business online tenant
Then, move it from SfBO to Teams.

Exchange 2013 to be built as Hybrid with Exchange online
Set up Cloud Voice mail for Online users.


Is there any order to ensure that production will not be impacted?


Any inputs would be of great help! Thanks!

I do go for Exchange first then do Skype on-prem to on-line to Teams


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.



Hi @Teshi80 


How did you go about decommissioning the on-premise Lync servers?


@Navishkar Sadheo 

not worrying about that as we're already on the way to MS Teams


so Skype On-prem > Hybrid > Teams Only mode


that way you then start to provision New users direct to Teams skipping the S4B steps etc.


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.


Overall goal for us is to get all users to MS Teams.


but the answer to the question you asked  is






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