<div>I really apologize for all the upgrade/CUWL/PUT questions but it's a minefield if you haven't done it in years.</div>

<div>Waiting to hear back on my UCSS for UCCX but menawhile I'm trying to plan out the rest of my PUT order.</div>

<div>Going from CUCM 6.1.3 to 8.6 - do I need to order all the intermediary upgrades as well? I'm not really 'upgrading' but installing 8.6 fresh. I'm sure there's a licensing minefield to navigate on this which will require me to submit a multitude of licensing requests and hope they get the entire chain right.</div>
<div> </div>
<div>CER 2.0 to 8.6 - Same question. I know I can't upgrade directly but I'm doing a clean install as well.</div>

<div>I have a handle on Unity/Uconn thanks to the group, particularly Ted! Well, one thing. What is the difference between HA ports and regular ports and do I need them for a HA deployment? </div>
