Yes, LitExtension supports migrating multiple-language content to OpenCart, covering products (name, description, and attributes) and categories (name and description).
That said, whether this works for your specific migration also depends on your Source Cart, since not all platforms support exporting multilingual content. For a free consultation about your specific case, please contact our Support Agents via live chat or email us at [email protected] to confirm the migration capability for your OpenCart migration.
