Every Customer's shopping cart have 25000+ prod

Hi there,

Looks like every customer have the same products on shopping cart

It seems that it referred to a Magento’s issue. You can learn more about it via these posts:

• https://magento.stackexchange.com/questions/304860/in-customer-edit-page-from-backend-in-shopping-cart-tab-why-all-quote-display-if

Please consider starting from the ground up again at your end with the steps as follows:

• Install a new fresh M2 instance
• Re-download the latest UB Data Migration Pro ver.3.2.3 and install on that new fresh M2 instance again.
• Then re-perform all steps of data migration as you did. Please make sure you don’t forget to check to migrate the ‘Sales Active Quotes’ in the settings of step #7 of our module.

Hi there,

I did check the “Sales Active Quotes” in my first attempt.

So, did you see any active quotes in the ‘quote’ table in your M2 database?

What is the version of your M2 instance? And did you use any other migration tool before using our migration tool in the first time?

Please consider re-performing all steps as suggested in my reply #1 at your end.

Hi there,

What is the name of that table.

I mentioned the name of that table in my reply #4: ‘quote‘.
Also, you can run the following SQL query in your M2 database to look for active quotes in your M2 database:

SELECT * FROM `quote` WHERE `is_active` = 1;

Hi there,

Showing rows 0 — 24 (808 total, Query took 0.0201 seconds.)

So, please consider reperforming all steps of data migration as suggested in my reply #1. 
And you should download the latest Magento core version here.
