Upgrading to Ecart 5
Hi, If I upgrade from Ecart4 to Ecart5, will I lose the modifications that I made to Ecart4. When I go in the Extension Manager to disable Ecart4 to Ecart5 it gives me a warning that I have made modifications and I should "package" the Ecart4 extension first. How do I package and extension? If I package the extension will it hold my modifications and work with Ecart5? If it will, how do I load my modifications into Ecart5? I just would not want the shopping cart to stop working.
