If your customers were migrated successfully but don't appear when you search in the Shopify admin, this is a known Shopify platform issue, it's not related to how the data was migrated.
Why Does This Happen?
After a large data import, Shopify's admin search index can become out of sync. The customer records are there and intact, but the search engine hasn't indexed them yet, so they don't show up in results.
How to Verify the Data Is There?
Before assuming something went wrong, try these checks:
Go to Customers in your Shopify admin and browse the full list. The customers should be visible there even if the search doesn't return them
Search by the customer's email in the Orders section. If they placed orders, they'll appear there
How to Fix It?
Contact Shopify Support and ask them to reindex your customer data. This is a standard request and typically resolves within 24–48 hours.
