Does this mean that I need to use the install files for a specific license to install/upgrade my sites? Or can I deploy the same files across each of my sites where they are licensed to operate? (ie download one zip file and use that same file to upgrade all of my licensed sites).
From what I can tell, the addon files are identical, so using the same install files on the sites I am licensed to install them on would work okay?
Note that I am not asking from a licensing point of view - I understand which products and addons I am licensed to use on which sites - it is merely a technical question from the point of view of minimising the amount of work required to maintain 8 different licensed sites and the mixture of addons installed on them.
