Hello Navin,

Unfortunately it not possible right now. You can migrate only from OpenCart 2.x:
http://extensions.arastta.pro/tools/opencart-2-migration

Regards.

I would suggest to migrate to OC 2 first using the following extension then Arastta:

http://www.opencart.com/index.php?route=extension/extension/info&extension_id=19572

I upgraded to OC 2.0.3.1 and dropped tables as per

https://arastta.org/forum/import-from-opencart-2-fails#reply-210 and
https://arastta.org/forum/import-from-opencart-2-fails#reply-215

When importing with the oc migration extension I am getting JSON errors.

Please supply the manual method of migrating to Arastta.

Some of the errors are attached with meaningful information changed.

Regards.
