I'm trying to migrate a CE 220.127.116.11 to CE 2.3.0 using the migration tool. I've managed to migrate the settings ok but when I try to migrate the data if get the following error.
[2019-03-11 14:02:16][INFO][mode: data][stage: data migration][step: Map Step]: started 7% [==>-------------------------] Remaining Time: < 1 sec In Mysql.php line 173: SQLSTATE: Integrity constraint violation: 1062 Duplicate entry '13-1052-0' for key 'CATALOG_CATEGORY_ENTITY_INT_ENTITY_ID_ATTRIBUTE_ID_STORE_ID'
I've seen posts about similar errors but nothing that relates to
CATALOG_CATEGORY_ENTITY_INT_ENTITY_ID_ATTRIBUTE_ID_STORE_ID. I realise that there is some kind of duplicate but can't find a way to identify and fix it.
Any help is really appreciated.
