Clarification about DELTA

Hi,
Please can you give me a clarification about DELTA migration.
In my case, I had done an intial migration with your extension 1 year ago.
During this year, my staff continue to work and
1/ update some product description, etc … on old products
2/ create new products.
I see that the DELTA migration create the new products but I would like to know what is the situation for old products (products already created by the initial migration but who have been edited and modified in production) => when I re-import a dump and re-apply a delta migration does it detect modification on these products ? update the content (image, description,etc …) ?
Thanks a lot for a clarification about this point.

Hi Bigand Jerome, 

1/ update some product description, etc … on old products

We wonder you referred to updating only products in Magento 1? Or you also updated products in Magento 2? 

If you have updated information of migrated products in M2, and if you run the delta migration with the ‘update’ mode in step #5 after the first migration, all the changes of migrated products in M2 will be loss (they will be overwritten by product’s information in M1). 

If you run the delta in step #5 without the ‘update’ mode, it will not affect the migrated products (means the products migrated in the first time). 
 
PS. You can learn more about the delta migration feature and the delta ‘update’ mode we mentioned above in this article
