Hi All,

I need your inputs in the lync server decommission from On premises environment. We have users enabled in Lync on premises server and the users got synced to Azure AD has enabled with MS teams license as well. For a short period of time, users were using both On premises lync and MS teams.

Please note, there is No Lync hybrid deployment in my environment. To avoid users from connecting lync on premise server, We have removed Skype for business client from all the users machine. Now we wanted to remove Lync ON premise servers from the environment, We are planning to use the below article for Lync server 2010 decommission.

Before i proceed with this article, I wanted to understand the following queries.

  1. In my current setup if i execute disbale-Csuser against my users does it cause any issues for users using MS teams.
  2. Does the steps covered in this article is suffice or any additional recommendation you want me to follow before lync server decommission.
  3. I am panning to shutdown the lync servers to understand the dependency part. Is there any better ways to achieve this.

    Configuring hybrid connectivity is a required step to migrate users from on-premises to the cloud and to ensure full Teams functionality. So before retiring the Lync server on-premise, please make sure you have completed the following steps:

    Step1:Move all required users from on-premise.

    Step2:Disable your hybrid configuration

    Step3:Move hybrid application endpoints from on-premise to online.
