hello all : I’m trying to upgrade from call manager 4.2 to 11.5 with quantity 250 total and operating the following models (7912,7911,7962,7960) I need to check if I can go through the SKU upgrade through UC-8.X-OR-EARLIER and total UPG-6K-ENH (qty 250) and then add new IP Phones through BE6K-UCL-ENH And I know that 7912 is only depreciated but the other phones will be valid so only these models will be replaced Can you help me to confirm if we can go through this SKU and replace only 7912 so we can implement the total project ?
