Data Migration Tool was used to migrate our Magento store from to Magento 2.3.3 successfully. Upon inspection of the Magento 2 DB, I found out the custom tables weren't migrated which are 6 of them. Is there still a possibility of Data Migration Tool being used again to migrate these custom tables? Or is exporting and importing them a better approach?

  • @Yo Yo Roshan, but the data migration is already complete so I am looking for a way to bring in those custom tables from Magento 1 to Magento 2 DB. Any suggestion? – CodeForGood Mar 18 at 8:08
  • You can create those custom tables manually in Magento 2 and then map those fields and then do migration only for those custom tables. Note: take a backup of your database. – Yo Yo Roshan Mar 19 at 7:39

I am not sure but It cannot done via Data migration as per as my idea.

I only for suggest

create all 3column data on a another table from Magento.

After data-migration,copy data from that table to using MYSQL

Ex :-

Table 1: id, name

Table 2: name, description
