Legacy URL mappings

This legacy-url-mappings.yml file manages legacy URL patterns for Elastic documentation, mapping the path of each legacy build URL to a list of documentation versions. It ensures that users can easily find previous versions of our documentation.

This example maps documentation that references `elastic.co/guide/en/elasticsearch/reference/ to Elastic Stack versioned URL paths:

en/elasticsearch/reference/:
  product: elastic-stack
  legacy_versions: *stack
		

stack anchor

Defines a reusable list of version strings for "stack" projects, e.g., [ '9.0+', '8.18', ... ].

mappings

A YAML mapping where each key is a legacy documentation URL path (like en/apm/agent/java/), and each value is a mapping with:

• product: Specifies the product or project type (e.g., elastic-stack, eck, ece, self-managed, etc.). Products must be defined in products.yml. See products.yml for more information.
• legacy_versions: A list of version strings that correspond to the available asciidoc pages.
