Good morning, I’d be grateful for some hints before I start experiments 
It’s about my blogpage in X. I built and customized it with Cornerstone, set it as post page and published, everything is fine. Now I need to adjust the image in my header. Of course this won’t work, as CS has no access any more, that’s clear.
But would there maybe be a workaround? E.g. if I duplicate the blog page will I then be able to use Cornerstone on that draft, adjust the picture and then set that new page as blog page? What will happen to my already published posts? Would there be a way to “move” them (including comments) automatically from the old blog page to the new?
It would be really great if you could help me to get my plan clear 
Thank you and regards
Karen
