Products are not displayed on the category page.
I completed data migration process and also do clean cache and reindex process.
And also check stock, quantity, visibility and etc.
But still product not display.
Can you please follow all the steps which are given in this link @ https://stackoverflow.com/a/2493774/8167656
Also, Can you please check the placeholder path and placeholder image configuration is properly set and it must be exist on /pub/media/catalog/product/images/placeholder/
Try to reset indexer once
php bin/magento indexer:reset
And reindex again and clear cache
php bin/magento indexer:reindex php bin/magento cache:clean php bin/magento cache:flush
