Hi JulienPct,
I did it in the way you wrote.
The Produkt-Images in my dev2 - Version I could not see, because in the img-url was something with dev and not dev2.
You write nothing about changing any table with image-urls. This means, that the url of the images are relativ - is this correct?
In the BO of my dev2-Version in an article I could see the product-image, but in the FrontEnd not.
To make the copy was not the big thing (only I had problems to see the fotos in the frontend).
The Problem was to use the Module "1 click upgrade". I used it to go back from 1.7.8 to 1.7.7 as the 8-version made a lot of stress.
After I clicked I had only a page with read writings about DB-problems. Also, the dev-version was defect.
I can not understand it. Because the parameters.php I changed in the dev2 - Version. I checked this by changing a produkt name. In dev it was the old name,
in dev2 the name I changed. So I knew, that I am working in the copied DB.
It could be this:
If the 1 click upgrade makes an "return" to older Version, it also will set the url in the ps_shop_url back to the old (dev) one.
I dont know. Probably there is a kind of DB-history-table. The module takes the data from there and change all table-data to this old-data.
I dont know how the Modules makes an "return to older Version".
yours
Daniel
