migrate:data [-r|--reset] config

[victor-v-rad]

Hi @fventurini

This #209 report looks quite similar. I assume you got the error because you disabled <integrity>Migration\Step\DataIntegrity\Integrity</integrity> in your config.xml and not resolved "Orphan records" in your Magento 1 DB

[fventurini]

You are right. I have to take db backup first of every data migration for eventual restore.
Now I am trying with fresh new mag2.1 and going to resolve furter problems.
Thanks

This happens when you re-try a migration (i.e. because the first attempt failed). I am yet searching for a solution to "reset" the db, as @victor-v-rad suggested. For me, I do not want to start with a fresh 2.x db because we already did quite some configuration.
Insight 1 Changing the prefix in map-eav.xml did change the error message to "offset 19" :)
Insight 2 Truncating relevant (?) tables as in http://blog.titechnologies.in/magento-2-x-how-to-clear-test-data-before-production/ lead me to the next error - I believe the original issue is resolved.

@fwolfst ,
Any fixes found? I am also facing the same issue

[terms999]

any update on this issue? I am facing the same.

[jafar247commerce]

@terms999 , no, still i didn't get any solution for this, one possible way is, need to restore the database then start migration again, it may help you, for me its resloved

[pjayramkumar]

I face this issue when i see "Class not found /Migration/Handler/EavAttribute/ConvertConfigurableAttribute" error during the migration.

To solve this i created the file and get the source from git repo of data migration tool 2.2 version

after that you need to import the fresh copy of database in destination site.

flush the cache and run the migration command from start.

[jloreto]

Greetings, I had a similar error but on line 492,
always use reset migrate: data -r
  and when it reaches this point the databases have already been modified. I had my backup and towards restoration.

I went to the line and ignored the Notice Exception with @

                $record['attribute_group_id'] = @$this->mapAttributeGroupIdsSourceDest[$record['attribute_group_id']];
                if($record['attribute_group_id']!==FALSE) {

Then all fine work

Regarding, need to restore the database then start migration again, I think that here https://oyenetwork.com/articles/data-migration-to-magento2-case-study/ worked differently, they did things like:

- 'INSERT INTO% s (% s) VALUES% s',
+ 'INSERT IGNORE INTO% s (% s) VALUES% s',
