Clara image question

I bought my Clara on Black Friday, learned how to patch it and made an image to upgrade to a larger sd card. Everything has been working great!

I like my Clara so much, I just ordered another since they might be discontinued and I plan to upgrade the sd card in it.

So, I was wondering if I could just make a current image of my original Clara to put on the sd card to put in the new one instead of going through the whole upgrade process?

It may or may not save much effort, but I'm curious which is the better way to go?

Thanks!
