Hello. I am ordering CUCM 12.5 upgrade on the MCE site and have a few questions regarding this. For part number UCM-12.5-SW-K9=, I show a quantity available that matches my total license count. Do I only need to order a quantity of 1 for the software upgrade? Also listed is my CUWL licenses, part number U-UCM-UWLS-10TO11=, which I assume I need to order as well and if so do need a quantity that matches my total licenses (70)? I already have a valid license for 12.x that I received about a year ago, and I got this by emailing cisco licensing support. Finally, my SWSS shows version 10 so how do I update this? Thanks!
