[ERROR]: Class accesscontrol/entity_attribute_backend_customergroups does not exist but mentioned in: eav_attribute.backend_model for attribute_id=198

I have added this to class-map.xml under folder

... <classmap xmlns:xs="http://www.w3.org/2001/XMLSchema-instance" xs:noNamespaceSchemaLocation="../class-map.xsd"> <rename> <from>accesscontrol/entity_attribute_backend_customergroups</from> <to /> </rename ...

But the error continues

I am running:

php70 bin/magento migrate:data -r -a ~/m2/vendor/magento/data-migration-tool/etc/opensource-to-opensource/

Please back up of Magento 1 database. Then remove that 198 number attribute id via database. And run Migration again.

Hope it will help you.

  • I would like to know why class-map.xml is not working. It should work for further classes that can not be erased. Thank you! Commented Apr 16, 2018 at 14:48
  • Are you using any tool for migration? Commented Apr 16, 2018 at 14:58
  • Magento database migration tool, this is where it requests to comment on class-map.xml, but it does not work. Commented Apr 16, 2018 at 20:28
