In this case you can make a copy of the website and install it on the local server. Then just make an upgrade there and upload the result on the live server.
Another option to try is to do a store import to 4.2.4, then do upgrades from that to the current level. A few more steps, but 4.2.4 store import has proven to be more reliable than te 4.3.x imports (which is why they stopped offering store import)

Yes, thank you. I'm going to try that, if I can find a cs-cart 3.0.6 version
I would certainly disable any 3rd party addons from V3 before upgrading. V3 and V4 are NOT compatible from an addon perspective and you will need to work with the addon vendor to get a V4 solution.
Well, I desabled all my addons in cs-cart 3.0.6, and the Store Import process is still blocked at the same level... No way to upgrade ! The log file is exactly the same !
If there are no errors in your PHP error_log file then I suggest you review your Apache error_log file to see if it terminated the underlying PHP process due to a timeout. But given that it returns to the admin panel, I would assume that you have NOT reached an Apache timeout. But some other event may have occurred so I would review the Apache logs.
If all seems okay, contact helpdesk and elicit their support.
Hello, I've contacted the Developpers who found a bug in a php file. And then, I managed to transfer my shop from cs-cart V3 to cvs-cart V4. Thank you !
