To make the Magento Migration process easy, there is a Data Migration Tool that is based on Command Line (CLI) that offers verification, logging, progress tracking and test functions.nofollow

To migrate data from your Magento 1 store to Magento 2 store, there are three modes of transfer:

  • Data Mode: Bulk migration mode that migrates data from Magento 1 database to Magento 2 database
  • Delta Mode: Catch up migration after the bulk data migration
  • Settings Mode: Migrates all possible configuration settings from Magento 1 to Magento 2

Note - It is necessary that the same versions of Magento and the Data Migration Tool are used. 

To check the Magento 2 Version, follow this step:

php <your Magento 2 install dir>/bin/magento --version

If you have downloaded the Magento 2 software using composer use the following command:

cd <your Magento 2 clone directory>
git branch

If you are in the developer branch, Firstly you must need to change this to a released branch before you continue.
