We need to consider the critically major functionality from Magento 1. Please consider below for M1 to Shopify migration:



- Prepare shopify frontend based on ready available shopify theme & tweak frontend design to match business brandings (We need provide some themes suggestions as per business need)



- Integrate marketplace functionality to allow different vendors to register, manage & sell products on the website. 3rd party shopify app from the same developer as M1 will be used to patch marketplace features.



- Allow admin to setup product wise shipping as a part of marketplace functionality (its part of marketplace plugin)



- Worldpay payment gateway integration. by default shopify does not support this natively so 3rd party app will be used for the same. App purchase needs to be done by client
