Customizing buy buttons and custom CSS disappears after upgrading to v3?
Are there ways to copy and paste from v1 customized code and buy buttons into v3 without having to re-do the customization again? It's too time consuming to figure out the changes needed between default and my own settings. Also, where and how to retrieve "Welcome to store" parag content that had been typed into previously in v1 to v3?
Appreciate your help.
