Error when migrating products

Hi there,

Message: Mage2SalesQuoteAddressItem: Row Weight is too long (maximum is 12 characters).

That issue because your M1’s database has at least one record which has bad data in the value of the row_weight field. The value’s length was over 12 characters and this was not allowed in Magento2 database structure.
To solve that issue, you could do with steps as followings:
+ Open the php file at path: pub/ub-tool/protected/controllers/Step7Controller.php
and find to the code lines:

foreach ($addressItem2->attributes as $key => $value) {
    if (isset($addressItem->$key)) {
        $addressItem2->$key = $addressItem->$key;
    }
}

and replace it by code lines:

foreach ($addressItem2->attributes as $key => $value) {
    if (isset($addressItem->$key)) {
        $val = trim($addressItem->$key);
        if (in_array($key, array('row_weight')) && strlen($val) > 12) {
            $val = substr($val, 0, 12);
        }
        $addressItem2->$key = $val;
    }
}

+ Once done, you could continue with data migration in the step #7 of our tool.

Mall.
