Hello.
Our site has zen cart 1.3.8 and has this cross sell plugin, Cross Sell - Just Another Cross Sell Mod (
https://www.zen-cart.com/downloads.php?do=file&id=477).
We will upgrade zen cart to 1.5.4 and was wondering if Cross Sell Advanced is a direct upgrade to the one we are using and if so will the installation be automatic after I uploaded the files or do I need to remove first any folder, files and database entries before installing Cross Sell Advanced.
Thanks.
