We currently support Microsoft Lync 2010 infrastructure. We are considering deploying Group Chat in order to provide persistent chat.
- Can not simply add the Group Chat services to the existing Lync 2010 Server, or does it require a separate server?
- If adding Group Chat to our existing Lync Server is not supported, what is the simplest recommended method to upgrade our Lync environment to single 2013 server with Persistent Chat enabled?
- If we upgrade to Lync 2013, do we have to get new licences for the accounts?
Thanks in advance.
