Migrate Products/Attributes/Combinations/Categories/Customers from Prestashop 1.3.7 in a fresh JTL Wawi Database.

We want to make a Relaunch from our very old 1.3.7. Prestashop based on a JTL Wawi installation with JTL Shop. We need a script wich make an export from our Prestashop Database, which can be imported with the JTL Tool "Ameise". We want to export following things: * All Products including all attributes, and all combinations with all informations * The full category tree * All active customers Its not neccessary to export the orders aswell. It is important that this export is a script (php is best i guess) which i can run again later for another update of the data (the development of the new shop take some time, so the source data will change (new orders, new products ...), so we have to run the export again short time before the relaunch will go live. You must have expert knowledge of prestashop structure, and you must have expert knowledge of JTL Wawi and JTL Import tool "Ameise". Thanks!
