having a wordpress theme installed on my website, along with a child theme, I have made some alterations to the parent theme as well to the child theme. I would like to start from scratch again, and keeping the option to use the old theme, when I am not working on the new one. Is it possible to have multiple versions of the same theme, ie. is it possible to install another "instance" of the existing pair of child and parent themes so that WP will allow me to switsch from the old set of themes to the new set, so that visitors to the theme will only experience downtime og reduced functionality while I am actually working on the new theme.
I suspect that I would be able to install another child theme, and name it differently in the child version of the style.css, but I am afraid that I have made some changes to the parent theme as well. So what I am asking is really if it is possible to install the existing parent theme with another name, and reference that name in a new child theme.
I do not see why not, but if my "experience" in this field has told me anything, it must be that I should trust the ideas, I believe to be obvious
