Magento – Magento Upgrade/Roadmap/Migration from 1.9 to 2.0

Lastest Magento 2.x version(2.0.1) ,Add a tool Code Migration Toolkit by which you can transfer your 3rd party extension of 1.x version to 2.x structure.

• You can Migrate Magento 1.x module structure to Magento 2.0 structure using Magento client Cli tool bin/migrate.php migrateModuleStructure
• Migrate Magento 1.x layout.xml Magento 2.0 structure file structure. (bin/migrate.php convertLayout

See the full steps of migration at Code Migration page

So,before migration,you should have strong knowledge of Magento 2.X structure Thus you can convert 1.x code to 2.x.You can understand those thing from code-migration process

But honesty ,you need to do lot of works for this achieve .

For Data migration from Magento 1 to Magento 2.

Your first step is Setting migrate,

command is:

php bin/magento migrate:settings /var/www/html/{{magento2}}/vendor/magento/data-migration-tool/etc/ce-to-ce/{{magento1 version}}/config.xml

All System -> Configuration settings are migrated in setting migrate. After completion of setting migrate, You need to check in Magento 2 Stores -> Configuration setting.

In migrate setting, From your database table, core_config_data have affected.

All Magento 1 settings are migrated to magento 2.

Thanks.
