Will the URL structure be maintained after the migration?
Each shopping cart uses its own way to build URLs for pages (products, categories, static pages, etc.). Unfortunately, Cart2Cart service does not support migration of the URL structure. You can maintain it manually if your Target platform supports flexible URL settings.You can also set up permanent redirect in your .htaccess files to avoid 404 errors on your original URLs.
Note: Nonetheless, Cart2Cart provides a possibility to migrate product and category SEO URLs within a limited number of shopping carts. Find more detailed information here.
