Preparing an upgrade from Magento 1

The differences between Magento 1 and Magento 2 are big. The code has a whole new structure with a lot of improvements but there is one big disadvantage. What to do if I want to upgrade my Magento 1 shop to a Magento 2 shop.

Magento created an upgrade tool that migrates the data of the Magento 1 database to the right structure for a Magento 2 database.

The custom modules in your Magento 1 shop will not work in a Magento 2. It is possible that some of your modules will have a Magento 2 version and depending of the module, the module author will have a migration tool to migrate the data that is in the module.

Getting ready

Before we get started, make sure you have an empty (without sample data) Magento 2 installation with the same version as the Migration tool that is available at:

https://github.com/magento/data-migration-tool-ce

How to do it

1. In your Magento 2 version (with the same version as the migration tool), run the following commands:

   composer config repositories.data-migration-tool git https://github.com/magento/data-migration-tool-ce
   composer require magento/data-migration-tool:dev-master

2. Install Magento 2 with an empty database by running the installer. Make sure you configure it with the right time zone and currencies.
3. When these steps are done, you can test the tool by running the following command:

   php vendor/magento/data-migration-tool/bin/migrate

   This command will print the usage of the command.

4. The next thing is creating the configuration files. The examples of the configuration files are in the following folder: vendor/magento/data-migration-tool/etc/<version>. We can create a copy of this folder where we can set our custom configuration values. For a Magento 1.9 installation, we have to run the following cp command:

   cp –R vendor/magento/data-migration-tool/etc/ce-to-ce/1.9.1.0/ vendor/magento/data-migration-tool/etc/ce-to-ce/packt-migration

5. Open the vendor/magento/data-migration-tool/etc/ce-to-ce/packt-migration/config.xml.dist file and search for the source/database and destination/database tags. Change the values of these database settings to your database settings like in the following code:

   <source>
   <database host="localhost" name="magento1" user="root"/>
   </source>
   <destination>
   <database host="localhost" name="magento2_migration" user="root"/>
   </destination>

6. Rename that file to config.xml with the following command:

   mv vendor/magento/data-migration-tool/etc/ce-to-ce/packt-migration/config.xml.dist vendor/magento/data-migration-tool/etc/ce-to-ce/packt-migration/config.xml

How it works

By adding a composer dependency, we installed the data migration tool for Magento 2 in the codebase. This migration tool is a PHP command line script that will handle the migration steps from a Magento 1 shop.

In the etc folder of the migration module, there is an example configuration of an empty Magento 1.9 shop. If you want to migrate an existing Magento 1 shop, you have to customize these configuration files so it matches your preferred state.

In the next recipe, we will learn how we can use the script to start the migration.
