How to migrate Magento 1x to Magento 2

How migration will work for you from Magento 1x to Magento 2?  Migration to Magento 2 involves four major components: data, extensions, themes, and custom codes/designs. Particularly, we should migrate Products, Categories, Customers, Orders, Configurations, CMS pages/blocks, Websites/Stores, Media assets and other custom tables/codes if you have. We’ll follow the migration strategy so that Magento 1x doesn’t not go down when migrating to Magento2.

Why migrate to Magento2

Magento 2 offers a range of flexible tools that cover any and all of your advanced marketing, SEO and catalogue-management needs – more so than ever before. It’s safe to say that the look, content and functionality of your online business are now easier to control than ever. So, Magento 2 is much better choice than Magento 1x. Though Magento company will be supporting the older versions for limited time, you need to have a plan to migrate to its newer version to become a market leader or pioneer of sorts in your niche.

Before starting migration

When starting the migration process, you need to ask yourself the following questions:

  • Should we bring all or part of the data?
  • If just selected part, which parts? Which part of data are going to migrate? How you determain what data is going to be migrated? Based on creation date? Based on status of product, customer? Or some combination of criteria? You can migrate data of some combination od criteria, because you might have some legacy data which you don’t want to migrate into new system. Instead, it is better to archive some data at somewhere on your site.
  • If we choose to bring over data on or after a certain date, which should it be – last 3 months, last 6 months, last year? Should it be all the data?
  • Should we clean data at source or destination? Should they cleaned on Magento 1x before migration or on Magento 2 after migration?

These are not the final set of question. More questions can be arisen before migration.
