Upfront and Upfront Builder


I have created two new themes, in builder. Both of them are modifications of Spirit and Guilie themes. Then I saved and kept the names. Now I am looking at the theme installed, they dont show up as if they are not being recognized. Now the main issue is, what would happen if the themes have updates, would that override my custom changes? I did not custom change any of the css core, mainly design and layouts, pages, names..images. it is very important for the upgrade process not to break our modified themes. I am building more themes for a project and I need my changes not to break the original themes and be a smooth transition from one version of the theme to another.
