Skype for Business 2015 Migration Step by Step

If you want to upgrade to Skype for Business Server 2015, and don't have a purely Lync Server 2013 environment, you will have to follow the migration path. The recommended path is to migrate from OCS or Lync Server 2010 to Lync Server 2013, then complete an in-place upgrade.

If you already have a purely Lync Server 2013 environment, you can skip straight to an in-place upgrade.
