Serial transfer

I do NOT know if this is still active... if it is, you may transfer the serial number

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
-you also may NOT sell/transfer if you used a program as the basis to buy an upgrade at a reduced price

i don't think so, but you should check with adobe support to confirm.  please update this after getting their answer.

there are 2 ways to contact adobe; chat and twitter (now x):

chat:
if you have or want to purchase a subscription, use a browser that allows popups and cookies
and click here, https://helpx.adobe.com/contact.html?rghtup=autoOpen
in the chat field (lower right), type AGENT
be patient, it can take quite a while to reach a human.

twitter/x:
tweet @AdobeCare

p.s. if you're contacted by anyone (via email or private message), it's much more likely to be a scammer than an adobe representative.
