I am migrating from Magento open source 1.9 to 2.3.3 the initial migration went well, however, I am trying to do delta migration by using Magento migration tool.

Running the delta command for migration tool gives me the error

Base table or view not found: 1146 Table 'magent7.catalog_url_rewrite_product_category' doesn't exist

Although, the table is existing, but I believe the tool doesn't add the database prefix before forming the query. Any help is appreciated.

Thank you

  • please access to file app/etc/env.php then check whether table_prefix is correctly config or not – user81967 Nov 18 '19 at 9:46
  • Yes, it is correctly configured @BlaireJohnson – Ninarrg Nov 18 '19 at 15:35
  • To make it more clear, that the initial migration went smoothly, i only had this issue when using delta mode – Ninarrg Nov 18 '19 at 15:41

run the reindexing

php bin/magento indexer:reindex

then upgrade setup

php bin/magento setup:upgrade

then flush cache

php bin/magento c:f

hpefully this helps

  • Thank you for your contribution. Unfortunately the solution didn't work. – Ninarrg Nov 18 '19 at 15:40

Finally, i could find the solution, i believe it is a bug in the migration tool and need to be fixed for the next update. However, the solution is as following:

  1. Edit the file


  2. replace the code in line #151

old code:


new code:


the previous change will add the database prefix to the SQL query.
