I have the full CS4 (Web Premium) program. What would it cost me to upgrade to a later version, say CS6 or even CC 2014?
I do not use PS every day to earn my living, but it is a side-skill that I am developing as an additional string to my bow.
There is no upgrade path from CS4 to CS6. You can only upgrade to CS6 from CS5.
As a CS4 owner you're entitled to a discount (first 12 months only) off your first year of Cloud membership.
What about from CS4 to CS5?
Adobe only sells CS6 and Cloud versions.
