I used data-migration-tool and did migration from 1.9 to 2.3 but lost all the products which were already in M2.
Before the migration there were around 2000 products and now they lost. I have backup of complete M2-database before migration.
How to get those product back in magento2.
I followed answer of @Mitro and it worked with some efforts but images are still not displaying though images can be open by media-url.
I tried command
php bin/magento catalog:image:resize but didnt work
