Why is my Shopify migration taking so long?
Shopify has implemented limits for orders’ migration. So, if you are currently using a trial or Partner development version of Shopify, it is possible to create only 5 orders per minute. Therefore, this limitation has been slowing down the process of Shopify migration.
To avoid such inconveniences, Cart2Cart recommends it’s users to upgrade to a paid plan before the Full Migration launch.
