Hi all, First off excuse the cross-post , but I wasn't sure if it should be the Exchange or NT list; To start forgive my ignorance here, but the last time I setup an MS communication server it was just that , 2005 Live communication server, which brings me to my question; I'm doing a DR plan for a client, and their admin tells me they have a Lync Server and a Skype for business server, I thought (and again forgive my lack of exp) that Skype for business was the replacement for Lync, if that is indeed the case why would they be running both? the only thing I can tell you is that they have about 50 phones
TIA
