  • Hi Alex Wang112

    If you want to upgrade to Skype for Business 2015, you can use the new In-Place Upgrade feature. In-place upgrade provides a one-click solution that backs up certificates, uninstalls server components, upgrades local databases, and installs the Skype for Business Server 2015 roles. There are two scenarios for In-place upgrade: Move user method (no downtime for user), Offline method (require downtime).

    The following steps show how to upgrade from Lync Server 2013 to Skype for Business 2015:

    1. Back up all databases before the upgrade.
    2. Make sure all services that are to be upgraded are in a running state.
    3. Upgrade and publish the topology file using the topology builder.
    4. Stop all services on all Front End servers.
    5. Install new prerequisites required for Skype for Business Server.
    6. On each Front End server, start the In-Place Upgrade.
    7. When the upgrade is complete, restart all services.
