Legacy code is a term used to describe computer code that is outdated, difficult to maintain, and no longer supported by its original developers. In the context of Drupal CMS, legacy code refers to code written for older versions of Drupal that is no longer compatible with the current version. Legacy code can be difficult to maintain and update, and may require significant effort to bring it up to date with the current version of Drupal.

Legacy code can be found in modules, themes, and other components of Drupal. It is important to note that legacy code is not necessarily bad code; it simply means that the code is no longer supported by its original developers and may require additional effort to maintain. In some cases, legacy code may be necessary to maintain compatibility with older versions of Drupal, or to provide functionality that is not available in the current version.

When dealing with legacy code, it is important to understand the risks associated with using it. Legacy code may contain security vulnerabilities or other bugs that can cause problems for your website. It is also important to consider the cost of maintaining legacy code, as it may require additional effort and resources to keep it up to date. In some cases, it may be more cost-effective to replace legacy code with newer, more up-to-date code.
