best way to upscale rough animation?

My computer is a mid range gaming laptop from like 4 years ago so its not the best for cpu limited tasks, for that reason i like to do my rough animation in lower resolution as to minimize buffer time during playback.

If i am doing a rough animation with multiple layers and assets, is there any clean way to upscale everything to proceed to lineart so i can refine it in higher resolutions?

I try to use transform masks to catch every frame when upscaling to a bigger canvas size but that isnt so straightforward when the parameters of each layer is not identical.
