Magento 2.0.18 is the final 2.0.x release. After March 2018, Magento 2.0.x will no longer receive security patches, quality fixes, or documentation updates.
To maintain your site's performance, security, and PCI compliance, upgrade to the latest version of Magento.

Migrate extensions

Migrate extensions from Magento 1 to Magento 2

Magento 1 extensions in most cases will not be compatible with Magento 2 code. Many extension providers offer updated versions of their products available for purchase or download on the Magento Marketplace.

Use this chance to review the list of extensions. To simplify future upgrades, install only the extensions that are required for your business.

There are no official tools available for migrating Magento 1 extensions to Magento 2. You must create a new extension from your old code using the Magento 2 coding standard.
