How to use Data Migration for us

Hi
We have some question about how to use your tool, is not support just question
We have a magento 1 with products we migrate to M2 some month ago but M1 still production
in M1 there is new product not in M2 and in M2 there is modified product not modified in M1
we work on M2 to modify products and on M1 to add products
if we do run as I understand this will add all product based on id it can create dupplicate product?
if we run delta as I understand it will add new product from M1

Question is delta will replace all modified M2 product wich are in M, and we loose all our modification?

Regards

Hi there,

Question is delta will replace all modified M2 product wich are in M, and we loose all our modification?

Yes, if you run the delta in step #5 with the ‘update’ mode by running the CLI command as follows:
php -f bin/ubdatamigration run --step=5 --mode=update;
 
If you run the delta migration in step #5 without the ‘update’ mode (using this CLI:
php -f bin/ubdatamigration run --step=5;) thenĀ it will migrate only newly added products in M1 which are added in M1 after the first migration.

But please note that if you checked the ‘KEEP ORIGINAL IDs’ setting in step #5 in your first migration, it might cause unexpected ID conflicts if you added new products in M2 after the first migration.

Regards,
Mall.
