Thanks Vimal.

What version of MySql shoould I be using for 1.x and for 2.3?

So I have to do upgrades in this order:

1.4.1.1

1.4.2

1.7.0.2

2.3

Is that correct?

Thanks,

Steve

Hi @steverino3,

MySql version should be 5.6 or 5.7.

For more system requirements you can also visit below magento2 docs.

Upgrade sequence looks perfect.

Hello! The steps you've described are really interesting. I agree with almost all of them. But I've got some questions.

1. How will you migrate the Magento 1 theme? If it is custom, you 90% need to install similar Magento 2 theme and only then customize it.
2. You can't migrate extensions: after migrating an online store to M2, every custom extension integrated with the Magento 1 platform becomes useless. The reason is due to a complete mismatch of the code and multiple conflicts which interfere with the platform operation. Plus there is no update tool that can help you migrate extensions. The only way you can do it is to find similar Magento 2 extensions, customize them. And if it is necessary, you need to write a custom extension from scratch. Here you can read more about the migration of Magento 2 extensions.
3. In order to migrate data with the help of Data Migration Tool, you need to migrate your 1.4 store to 1.6.0.0. The tool allows migrating orders, customers, products, and categories
4. Of course, you can migrate the custom code.
