Let me just mention that, in the interests of future-proofing and preservation, I’m going to attempt to export my projects into ProRes and add them to my Drive so others can access and even use them. FCP7 will not run on whatever computer I get next, so I don’t want things to hinge on an old computer continuing to work forever. This resolution follows a vain attempt to virtualize an older OS.

Rogue One is there now, and hopefully the others to follow. The ST shouldn’t be a big problem, but the prequels may or may not be possible.
