there's no way (unfortunately) for adobe to automatically transfer your cc files from one account to another. but assuming you are using the same account for your plans (ie, same adobe id), i don't think you would lose those ps and lr data.
if i were you i would want to ensure that's the case and not just accept a well-meaning "i think". to that end, contact adobe support and see if they can say with more certainty.
using a browser that allows popups and cookies, contact adobe support during pst business hours by clicking 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
p.s. if there's still some doubt, or you just don't want to risk a problem, transfer all the ps and lr cc files to your personal computer.
p.p.s. you should also check to see if adobe support can waive the early cancellation fee for cancelling your photography plan (in view of the fact that you have an all apps plan).
