I just came to know that after 29 june 2021, any new store on shopify will have DAWN as default theme instead of DEBUT. I have created an app on shopify store which is creating some new files for a theme(eg. js files) and update some liquid files. I know from the articles that i have to manually copy the changes to new theme. But is there any way where I can automate this procedure(like I can copy my changes to the new theme).
And also I have added some changes in respective liquid files( in DEBUT theme): search.liquid, product-template.liquid, cart-template.liquid
But I am not able to find these files in DAWN theme. How should I handle these scenarios as I could see that after changing the theme, some of the files are being replaced by some new files. Is there any way to handle this , as user can apply any theme from theme store.
