Delta Migration PHP Error

Hi there,

changed Line 302 and 315 to: public function offsetExists(mixed $offset): boolI don’t get any errors anymore but migration does not start and I also can’t UB Datamigration in Admin.

Please discards all the changes you mentioned in the code of our module. And then provide me information about your instance:
+ Admin credentials and URL to the backend of your M2 instance
+ SSH credentials and the path to the M2 root folder
+ Do you upgrade the Magento instance or upgrade the PHP in your M2 server after the first migration with our migration tool?

I will help to check further and get back to you then.
 

Regards,
Mall.
 

Hi there,

I couldn’t log in to the backend of your site with the admin credentials that you provided: http://prntscr.com/_Naw6DlwPXT9

I didn’t changed magento or PHP. I installed extensions and Themes and they had a lot of bugs because of PHP 8.1.7 but they should be fixed now.

The SSH credentials are fine. To handle cases with PHP 8.1, I have added more tweak code in the PHP file at the path: /home/seedsat/public_html/magento244/pub/ub-tool/index.php
Please continue with delta migration in step #7 at your end by running the following CLI command:

php -f bin/ubdatamigration run --step=7

Let me know how it goes.

Mall.
 
 

Hi there,

Have the same error again:
[seedsat@sh56 magento244]$ php -f bin/ubdatamigration run --step=7

What happens if you switch to using PHP 7.4.x for data migration?

Hi there,

Magento 2.4.4 is not working with 7.4 and your extension should work with PHP 8.1 for actual Magento Versions.

So, can you switch to PHP 8.1.4 version? Because we tested and our migration tool working fine in this PHP version.

Mall.

Hi there,
I have added more tweak code in our module to disable the PHP warnings you mentioned.
And now you can continue with delta migration in step #7 at your end:

Hi there,

[Processing][delta] in step #7: Error: Attempt to assign property “conditions_serialized” on null in /home/seedsat/public_html/ magento244/pub/ub-tool/protected/controllers/Step7Controller.php:948

It seems that your M1 database has at least one bad data in the value of the ‘salesrule.conditions_serialized’ field.
To handle that case, I have added more tweak code in step #7 of our module. Please continue with delta migration in step #7 by running the CLI command like the following (no need to run with ‘update’ mode this time)

php -f bin/ubdatamigration run --step=7

Hi there,

I deleted sales rules after migration in M2 can this be the problem?

Yes maybe.

[Processing][run] in step #7: Error: Attempt to assign property “actions_serialized” on null in

That is another case. It happened with the ‘salesrule.actions_serialized’ field.
I have added more tweak code to handle that case. Please continue by running the following CLI command:

php -f bin/ubdatamigration run --step=7

Hi there,

[Processing][run] in step #7: Error: Call to a member function save() on null in /home/seedsat/public_html/magento244/pub/ub-tool/protected/controllers/Step7Controller.php:958
Stack trace:

That is strange. It may be related to the deleted migrated sales rules in M2 that you mentioned above.

Let’s try doing these steps:
1. Run the CLI command:

php -f bin/ubdatamigration clean --step=7;

2. Once done, you continue with delta migration in step #7:

php -f bin/ubdatamigration run --step=7

Hi there,

Status: fail
Message: CDbCommand failed to execute the SQL statement: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry ‘1803’ for key ‘PRIMARY’. The SQL statement executed was: INSERT INTO `mgd8_sales_order` (

That issue is because you checked ‘KEEP ORIGINAL IDS’ in settings in step #7. And after the first migration, your M2 has at least one newly added sales order. To continue with delta migration in step #7, you must delete all sales order added in M2 which was not migrated by our migration tool. If you can do this, you can try with steps as the following:
1. Run the following SQLs in your M2 database

Delete From salesrule Where rule_id NOT IN (Select m2_id From ub_migrate_map_step_7 where entity_name = 'salesrule');
Delete From salesrule_coupon Where rule_id NOT IN (Select m2_id From ub_migrate_map_step_7 where entity_name = 'salesrule');
Delete From quote Where entity_id NOT IN (Select m2_id From ub_migrate_map_step_7_quote where entity_name = 'sales_flat_quote' OR entity_name = 'sales_flat_quote_active');
Delete From quote_item Where item_id NOT IN (Select m2_id From ub_migrate_map_step_7_quote_item where entity_name = 'sales_flat_quote_item');
Delete From quote_address Where address_id NOT IN (Select m2_id From ub_migrate_map_step_7_quote_address where entity_name = 'sales_flat_quote_address');
Delete From sales_order Where entity_id NOT IN (Select m2_id From ub_migrate_map_step_7_order where entity_name = 'sales_flat_order');
Delete From sales_order_item Where item_id NOT IN (Select m2_id From ub_migrate_map_step_7_order_item where entity_name = 'sales_flat_order_item');
Delete From sales_order_address Where entity_id NOT IN (Select m2_id From ub_migrate_map_step_7_order_address where entity_name = 'sales_flat_order_address');
Delete From sales_invoice Where entity_id NOT IN (Select m2_id From ub_migrate_map_step_7_invoice where entity_name = 'sales_flat_invoice');
Delete From sales_invoice_item Where entity_id NOT IN (Select m2_id From ub_migrate_map_step_7_invoice_item where entity_name = 'sales_flat_invoice_item');
Delete From sales_order_grid Where entity_id NOT IN (Select m2_id From ub_migrate_map_step_7_order where entity_name = 'sales_flat_order');
Delete From sales_invoice_grid Where order_id NOT IN (Select m2_id From ub_migrate_map_step_7_order where entity_name = 'sales_flat_order');

2. Once done, you continue with delta migration in step #7:

php -f bin/ubdatamigration run --step=7

Hi there,

[Processing][delta] Step #7 migration completed with 37 record(s) in the ‘sales_flat_order’ table.
Error: Attempt to assign property “customer_tax_class_id” on null in /home/seedsat/public_html/magento244/pub/ub-tool/protected/controllers/Step7Controller.php:1906

Let’s try with steps like the following:
1. Running the CLI command:

php -f bin/ubdatamigration clean --step=7

2. You continue with delta migration in step #7:

php -f bin/ubdatamigration run --step=7

Hi there,

Message: Property “Mage2SalesOrder.paypal_ipn_customer_notified” is not defined.

This is because your M2 instance has not had the core module named ‘Magento_Paypal’ installed.
Please consider installing that module. Once done, you can continue with data migration in step #7 by running the CLI command:

php -f bin/ubdatamigration run --step=7

Mall.
