There is no upgrade path from a suite to an individual product.
You can buy InDesign CS6 for $700 or you can subscribe to InDesign CC for $20/month.
Your CS5 license also is good for one year intro rate of $29.99/month for the entire Creative Cloud package.
Thanks for this. Can I upgrade my CS5 to the most recent version of CS5? I didn't ever keep up with any upgrades which came along. I have a document which needs more recent plug-ins than I have at present. I am only a very part time/volunteer type artwork for local businesses so don't want to spend my money (or theirs!) if at all possible. Thx
If it was created in CS5 you should be able to open it. If you’re getting
missing plug in errors, it was created in a newer version.
Thanks, much appreciated
