You have a Microsoft Lync Server 2013 deployment. Some users use Enterprise Voice. You plan to migrate to Microsoft Teams. You need to design a migration solution. The solution must minimize the impac

There is no supported direct migration path from Lync Server 2013 to Microsoft Teams, making this option technically invalid.

Migrating only Enterprise Voice users to Skype for Business while leaving other users on Lync creates a fragmented environment that increases rather than minimizes user impact.

Moving non-Enterprise Voice users directly to Teams while Enterprise Voice users remain on Lync 2013 splits the user base across incompatible platforms and does not represent a minimally disruptive solution.

Performing an in-place upgrade from Lync Server 2013 to Skype for Business Server creates a supported intermediate platform before the final Teams migration. Microsoft's documented upgrade path requires this intermediate step because Lync 2013 cannot migrate directly to Teams. This staged approach minimizes user disruption by keeping users on a familiar interface before the final transition.
