I'm getting ready to go live on Shopify (store previously hosted on another platform). but before the domain is transferred there are new orders to import into Shopify since the original data migration (peformed by Cart2Cart). I want to add these new orders to Shopify but not overwrite all of the already imported orders. AND I would like to retain the order numbers from the previous platform (as the original migration did). I have a csv file of the new orders however I do not feel comfortable doing this myself or having Cart2Cart re-import the data - I'm concerned they (or I) will overwrite all the current orders and/or not be able to retain the old platform order numbering.
I'm anxious to tranfer the domain as soon as possible. Please provide a quote and an idea of how quickly you could complete. Thanks.
