I looking for the migrate Product custom options records from magento 1.7 to magento 2.x I have have migrated all the data from magento 1.7 to magento 2.2.6, but custom options not showing.
Please check in the product editing page to see whether custom options are showing. If they are there but not on the front end, go checking the catalog_product_entity table. In this table, there is a has_option field, this field must be set to 1 in order for the custom options to show up
Let me know if this helps
