The client currently runs View 11.0 (out of support) and wants to upgrade to the highest release level possible.
Release : 12.2
Component : CA View
View 12.0 and Deliver 12.0 were "unlocked" so that the client could download those products.
Those products were unlocked, rather than releases 12.1, because from View 11.0, the highest next point of upgrade would be View 12.0.
From View 12.0, the client would then be able to upgrade to View 12.2, which is current.
During an unlock, the products are available for only a small period of time, where download needs done during that window.
