We have Lync server 2013 in our envirenment and approx. 700 Polycom VVX 310 IP Phones. As of now firmware version is 220.127.116.110.
We are planning to upgrade it to 5.4.2 Rev D. Can we directly upgrade to 5.4.2 Rev D ? Also i see the noted in download link "The use of Polycom UC Software versions 5.4.2 Rev D requires an individual license per device which can be used with Microsoft Skype for Business and Microsoft Lync environments"
Do we need to purchase new licence to use 5.4.2 Rev D?
