Old versions

[xavierh185657]

Hello I would like to know 

what should I do with my old versions of Adobe, I still have the boxes with the CDs, the oldest version is CS3?

Thanks Xavier

The CS2-CS3-CS4 activation servers have been removed from service, so those are dead versions

CS5-CS6 could be sold, with an official license transfer

Transfer (selling or giving your software away) https://helpx.adobe.com/x-productkb/policy-pricing/transfer-product-license.html
-you may NOT sell or transfer an Education serial number

Of course, a new Mac will not run an old program
