Possible to only migrate products?

Hi Ted Sundin, 
Thanks for contacting us. 
We’d like to clarify as follows: 

Is it possible to only migrate products? Products will be without category ofc, I understand that.

With the current workflow of our module, you still need to migrate related data objects. That means, in order to migrate Products, you need to proceed with all steps from Step 1 to Step 5 (you can learn more about these steps in this article).
 
After the migration, you can disable or delete un-used categories. However, please note that after you disable or delete categories, you still need to assign the categories for migrated products in M2.
 
If re-assigning categories for the migrated product in M2 is not a problem for you, you can run the data migration as noted above from Step 1 -- 5, then disable/delete unused data.
 
PS. You should not delete migrated categories in M2 if you still plan to run delta migration for these categories after the first migration.

Hi Ted Sundin,
We’d like to follow up further below: 

Do I need to delete current stores still or will new stores be created same as Magento 1?

Our module supports migrating data to your current M2 instance with existing sample data. So, removing the current Stores in M2 before running migration is optional.

Can I have my current categories in Magento 2 if they have a different Root category?

Yes, you can keep the existing categories in your M2.

Hi there,

Isn’t it possible to run the product migration again? 

Yes, you can try these steps:

1. Run the following SQL query in your M2 DB:

UPDATE `ub_migrate_map_step_5` SET `offset` = 0 Where entity_name = 'catalog_product_entity';

2. And then, you run data migration in step #5 using the CLI command:

php -f bin/ubdatamigration run --step=5

Hi Ted Sundin,

Message: CDbCommand failed to execute the SQL statement: SQLSTATE[HY000]: General error: 1364 Field ‘sku’ doesn’t have a default value. The SQL statement executed was: INSERT INTO `inventory_source_item` (`quantity`, `status`, `source_code`) VALUES (:yp0, :yp1, :yp2)

That issue occurred because your M1 DB had at least one product that didn’t have a value of SKU attribute.

Please try the steps below to handle that case:

1. Open the PHP file at: pub/ub-tool/protected/controllers/Step5Controller.php
and find the code lines:

//migrate product stock item
$this->_migrateCatalogProductStockItem(
    $product->entity_id,
    $product2->entity_id,
    $product2->sku,
    $keepOriginalId
);

and then replace it with:

//migrate product stock item
if (empty($product2->sku)) {
    $product2->sku = "SKU-{$product2->entity_id}";
}
$this->_migrateCatalogProductStockItem(
    $product->entity_id,
    $product2->entity_id,
    $product2->sku,
    $keepOriginalId
);

2. And then, you continue with data migration in step #5 using the CLI command:

php -f bin/ubdatamigration run --step=5

Hi there,

1 exception(s): Exception #0 (Magento\Framework\Exception\LocalizedException): The “componentType” configuration parameter is required for the “price_per_unit” component.
I get this error is related to MageWorx Advanced Product Options plugin. Anything you know how to fix?

That issue related to the settings of the custom product attribute ‘price_per_unit’ (please see this post for reference: 
https://stackoverflow.com/questions/64871339/componenttype-error-when-clicking-edit-product-in-magento-2-3-4) 
 
Since this associates with MageWorx product, please reach out to the team for further help.
