FAQ on magento 2

When is ‘end of life’ for Magento 1?

All official support ends at the end of June 2020.

The official announcement from Adobe can be read here

Why should I upgrade?

Magento 2 is a far more powerful ecommerce platform that provides improved performance and scalability, tighter security, integrated marketing functionality, not to mention being much easier to manage and update.

Your customers will benefit from a smoother, faster shopping experience, with more payment and delivery options, which can result in a higher rate of conversion.

What happens if I don’t upgrade?

At the end of June this year, there’ll be no further official support, updates or security patches.

our website won’t suddenly stop working and you can remain on Magento 1 as long as you wish. However there are some risks associated that should be strongly considered.

Security risks

Updates will cease at the end June 2020. So there’ll be no protection for your site against vulnerabilities that are discovered after this time.

This not only puts your website at risk of being compromised by malicious activity but also puts your customers’ data at risk. So you could easily fall foul of data protection legislation and PCI-DSS compliance requirements.

Out of date extensions

The main focus for Magento developers is building extensions for the current platform (Magento 2). Extensions built for Magento 1 may be unsupported and become out of date.

If your site relies on extensions for transactions or extra functionality, then you could quickly start to see performance issues and security risks from vulnerabilities discovered in outdated extensions.

Lack of resources

Delaying your decision to move to Magento 2 might leave you with fewer options in terms of developers that are available to work on your project. There are a lot of Magento 1 sites to migrate and there’s a very limited supply of good Magento 2 developers.
