We have a user who currently has a box (serial key) version of Adobe CS6 installed on his machine. We now have a number of cloud licenses available and I want to move hm to a cloud license so that we can install the apps available from the cloud.
Do I need to uninstall the previous version of Adobe CS6 and then re-install from the cloud or can I just re-license the software using the creative cloud for desktops application?
There is no need for it. You can run CS6 Perpetual and CC on the same machine without uninstalling CS6.
