There's been a lot of confusion as to the support lifespan and process for Magento 1 merchants over the last few years. This month Magento announced on their blog that Magento 1 support would continue until 2020.
Joe Ayyoub, Director of Support Operations, Magento, announced in the Magento blog article: “We understand that many of our Magento 1 merchants need additional time to make the transition to newer versions of Magento. To that end, our software support policies ensure that those customers have the time and confidence to upgrade when it is right for their business.
"For Magento Commerce 1 [formerly known as Enterprise Edition], we are providing software support through June 2020."
“In particular: For Magento Commerce 1 [formerly known as Enterprise Edition], we are providing software support through June 2020. Depending on your version, software support may include both quality fixes and security patches.... For Magento Open Source 1 [formerly known as Community Edition], we are providing software security patches through June 2020 to ensure those sites remain secure and compliant.”
Merchants will need to review the Magento Software Lifecycle Policy and Magento Open Source Software Maintenance Policy to see which versions of Magento 1 continue to receive software security maintenance.
It was widely rumoured that support for the Magento 1 platform would cease in 2018, as the company looked to encourage the migration onto the new and improved Magento 2. That support's now being extended to accommodate the host of merchants still in the process of migrating.
It's also been made clear that the support and security maintenance Magento are offering only applies to Magento software and does not apply to third-party extensions or customisations, and that modifications to the Magento codebase remain the responsibility of the merchant.
"While we’re committed to supporting the success of all merchants, the time to upgrade to Magento Commerce 2 is now."
The same blog article went on to say: “While we’re committed to supporting the success of all merchants, the time to upgrade to Magento Commerce 2 is now. Magento Commerce 2 delivers superior cloud-hosted performance at scale, freedom from IT bottlenecks with creating, scheduling, and launching compelling content, and true business intelligence capabilities.”
Magento 2 now has more than 2,000 available extensions, new versions launching quarterly, and now boasts over 30,000 ecommerce sites, with many more being launched per month. So while Magento is not pulling the support rug out from under Magento 1 merchants just yet, it's clear that the transition to Magento 2 is still very much the expected and recommended path for all merchants that wish to continue using the platform into the future.
