I am trying to Migrate a Magento 1 store to Magento 2 store. I am getting below error while migrating.
[2018-11-14 13:24:37][WARNING]: Foreign key (FK_CATALOG_EAV_ATTRIBUTE_ATTRIBUTE_ID_EAV_ATTRIBUTE_ATTRIBUTE_ID) constraint fails on source database. Orphan records id: 121,164 from `catalog_eav_attribute`.`attribute_id` has no referenced records in `eav_attribute`
[2018-11-14 13:24:37][WARNING]: Foreign key (FK_CAT_PRD_ENTT_INT_ATTR_ID_EAV_ATTR_ATTR_ID) constraint fails on source database. Orphan records id: 121 from `catalog_product_entity_int`.`attribute_id` has no referenced records in `eav_attribute`
[2018-11-14 13:24:37][WARNING]: Foreign key (FK_EAV_ENTITY_ATTRIBUTE_ATTRIBUTE_ID_EAV_ATTRIBUTE_ATTRIBUTE_ID) constraint fails on source database. Orphan records id: 121,163,164 from `eav_entity_attribute`.`attribute_id` has no referenced records in `eav_attribute`
In this regard I would like to use below section of `config.xml` file.
<step title="Data Integrity Step">
<integrity>Migration\Step\DataIntegrity\Integrity</integrity>
</step>
I am new in Migration. How can I use that section ?
