Let’s take a look at how to upgrade from Magento 1 to Magento 2. Follow the steps below.
Step 1: Theme Migration
Remember that, you cannot directly migrate your Magento 1 theme to Magento 2. However, to accomplish such an objective you’ll have to consider performing any one of the following things:
You can hire a frontend designer or developer to create a unique and new theme for Magento 2. Also, here you must consider making the theme responsive.
Secondly, you can install a Magento 2 theme from the Magento ecommerce Marketplace.
Step 2: Migrate Extensions
Once you’ve migrated your theme or created a new one for Magento 2 installation, next you should migrate the extensions installed on your existing site to the new version. However, make sure to move only the relevant extensions to Magento 2. Also, keep in mind that at times Magento 1 extensions might not work with Magento 2. Simply put, you might experience compatibility issues when trying to integrate some extensions of Magento 1 version to the new version release.
