I am interested in upgrading from 1.39 to 1.51. But I don't know where my original version is. Can I upgrade without knowing the add-on and changes from the original version? back story - I bought a business that uses zen cart, but I am having problems finding the original version. I use EWD hosting and I have checked the files in file manager but I can't find it. can i look at the add-on folder and find how the current version has been changed?
