I tried to migrate producs from magento 1.9.3 to magento 2.3, everything is okay until I check the configurable product. Then I found associated product on the configurable product is null but the simple product is already migrated like this below screenshot:
So how I can migrated the links of configurable with associated product too. If someone already have same issue and solved it, please advise.
update :
here is my catalog_product_super_link table it the relation data has been migrated, but it not applied on the website product



catalog_product_entity_inttable magento 1 so I try to copy manual from magento 1 table to magento 2 table only for color attribute and my problem solved.colorattribute. In my case (and i think in most cases) the problem was, becausecolorattribute is not in defaultattribute set. And after migration it wasn't assigned to any attribute set. The solution was to assigncolorattribute todefaultattribute setbefore running the migration and everything went correct.
