Did you migrate settings or data before migrate delta?

I am currently in the same process as you, that mistake I made yesterday also to me when doing a migrate data before doing a migrate delta. What I did was go back to a previous backup of the database and then do a delta migration.

Now the problem that I have Mismatch of entities in the document can be seen in the page of the data migration tool https://github.com/magento/data-migration-tool/issues/539

So I would start by going back to a previous Magento 2 backup and then doing a Delta from the Magento 1 Database.

  • Yes, I have migrated settings and data before migrate delta. – Gagandeep Singh Jun 19 '18 at 7:37

maybe your migration tool is outdated?

Possible fix:

  • yes, i didn't updated it from 2.2.2 to 2.2.3, I will try after updating it. – Gagandeep Singh Jun 18 '18 at 5:30

Have you managed to advance something? because we are in the same situation and we have problems when doing the Delta to migrate new clients, invoices and credit bills.

[root@host .com]# php bin/magento migrate:delta "vendor/magento/data-migration-tool/etc/opensource-to-opensource/1.9.2.4/config.xml" --reset Reset the current position of migration to start from the beginning

  • Currently I am offline with this task, When i'll continue with this task then i also mention updates here. In your case it seems like mismatch fields error you have to skip this by editing xml files of data migration tool. – Gagandeep Singh Jun 19 '18 at 7:34
  • Finally, I have installed emagicone.com/products/solutions-for-magento-commerce and at the moment clients migrated and updated, the same thing all the products and I am now with the orders. You have 14 trial days, enough to migrate all the data from Magento 1 to Magento 2. – Juan Dosil Jun 22 '18 at 13:37
