I am working on magento migration using default magento migration tool.

Followed all the steps and migrated data successfully.

I followed the below procedure to migrate data:

  1. Took the dump of M1 Production site database to local

  2. Installed M2 new instance.

Configured source and destination in config.xml file of migration tool

Data migration happen successfully.

Now i need to migrate the changes, Did the following changes.

  1. Took the dump of M1 Production database into local(After 1 week of data migration)

Configured source and destination in config.xml file of migration tool

Then run the below command to migrate the changes.

   php -d memory_limit=10G bin/magento migrate:delta --auto vendor/magento/data-migration-tool/etc/opensource-to-opensource/1.9.3.4/config.xml

I am facing below error,

  Delta Delivering Failed - Deltalog for customer_entity, is not installed in Magento 2

Which means Data Migration Tool creates triggers in the source database. they are used in delta migration. source ->Delta Delivering Failed - Deltalog for customer_entity, is not installed in Magento 2

But this time the database is different where i took the latest dump to local and trying delta migration, which is making problem for me.

How can i migrate changes once the data transfer is done successfully.

Can anyone help me on this please. Thanks
