I am migrating the data from Magento 1 to magento 2.4.1 by running the following command

php bin/magento migrate:data --reset vendor/magento/data-migration-tool/etc/opensource-to-opensource/1.9.0.1/config.xml

But it throws the following error and stopped migration

SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '137-24' for key 'CAT_PRD_ENTT_MDA_GLR_VAL_TO_ENTT_VAL_ID_ENTT_ID'

please refer to the attachment

  • Hey, backup the database, but I think you can truncate that table with no problem should be catalog_product_entity_media_gallery_value_to_entity or something similar, when I did the migration I truncated that table

Add the catalog_product_entity_media_gallery_value table inside the ignore document section of both source and destination in map.xml, and then proceed migration it works like charm
