Delta Migration Magento 1 to 2

Delta migration simple meaning is latest database new order, new customer , invoice etc. migrate your store.

A Delta Migration allows the resubmission of a mailbox in order to perform a differential migration pass. MigrationWiz will automatically find data that hasn't yet been migrated, and migrate only that. In other words, a Delta Pass will find and migrate residual data.

   Delta migration is used in the last stage of the migration process to move data that was created or       changed since the last time you migrated data.


   Migrate delta: it will run append incremental changes from magento 1.9.x to 2.x

   To migrate incremental changes, use the following command:

   # php bin/magento migrate:delta vendor/magento/data-migration-tool/etc/ce-to-       ce/1.9.2.1/config.xml


   To stop this process you need to CTRL+C .


    Thanks.
