How to Upscale a Mask (not enlarge it) and use it in an newly upscaled layer?

[Letty2019]

I bet this one is really easy, or impossible.  

How do I copy and past a mask made on a 4:3 layer, then apply it to another layer that is upscaled?  (same clip in both layers, the new upscaled layer is now 294%)

Thanks so much!

There is a mask resizer script on AEScripts.com. Give that a whirl.

Thank you very much for that info.

I will give it a whirl.   I'm surprised that there isn't something like this in AE already?  Seems like something that people can use.

Thank you,
