Answer 1

First check this link :- https://github.com/magento/data-migration-tool/issues/235#issuecomment-321923437

Solution is to rename all values containing the name "Default" in "attribute_value_name" field of eav_attribute_set table to "Default_x" in the Magento 1 database and run the migration from scratch.

In my case, there were 9 records with name "Default". So I renamed them to Default_1 to Default_9 and it worked perfectly!
