I would say no.

Your serial key for Photoshop Elements is valid for 2 systems. But only for installtion of the same version, in your case 2022. If you use a license to update to a newer version the key becomes invalid.

Once I've upgraded, can I use, sell, or transfer the previous versions of the software?

No. Purchasing an upgrade to your product extends your existing license to cover the new version of Adobe software. It does not provide you with two separate licenses for the old version and the new version. 

If you purchase a new license, rather than upgrade your old software, you are permitted to transfer your old license—that is, as long as you did not purchase the original license with a volume licensing arrangement.
