After migration, we placed order, create product and test everything. Now when we trying to run delta migration (also tried -a it is giving error like:

Its seems issue with related product link

Thanks in Advance!

Answer 1

I found Solution, It was due to related products.

After migration, We created product in Magento 1 and assign related product to those products.

Issue was related products assignment in magento 1

When We removed, related product from Magento 1 for newly products, above error has gone!

after migration we again assign related product in Magento 2

Hope above will help to others!
