I want to migrate data(only customers, categories and coupons) from magento 220.127.116.11(CE) to magento 2.1.0(CE)
I am following Steps from - http://devdocs.magento.com/guides/v2.0/migration/migration-tool-install.html for data migration.
What I understood is in 1. m2project/vendor/magento/data-migration-tool/etc/ce-to-ce/18.104.22.168/config.xml I defined source and destination database table and map.xml And after that I run setting, data and delta migration
I am stuck with step data migration with error :
SQLSTATE: Integrity constraint violation: 1062 Duplicate entry '1-Migration_Default' for key 'EAV_ATTRIBUTE_SET_ENTITY_TYPE_ID_ATTRIBUTE_SET_NAME'
If any help to solve this error, will make me proceed migration.
Also, I am unclear about :
What exactly data it transfers other that customers,orders, products.
If I have multiple stores in magento1.9 and here in magento2.1 I want single store in that case what will happen? because product will be having dependency on store.
I want yo know how to migrate only customers, categories and coupons.
