# Legacy Framework Mapping

<br/>

The legacy Well-Architected Framework was organized around three capabilities — **Trusted**, **Easy**, and **Adaptable** — each with its own sub-pillars. The current framework reorganizes that guidance into five pillars. This page maps each legacy sub-pillar to the single file where its guidance is now **most directly addressed**, so you can jump straight from an existing concept to its current home.

Each destination links to a live page. The new framework splits several sub-pillars across more than one pillar, so we link the primary (most-addressed) home and call out any secondary homes in the notes.

## How to read this map

- **"Now Most Addressed In"** is the single file where the bulk of that sub-pillar's guidance now lives — the best first click. It's not the only place the topic appears.
- **Splits** are called out in Notes when a sub-pillar was deliberately divided across pillars (for example, Legal Adherence: infrastructure/security in Trust, personal rights in Fairness).
- **Engaging (Streamlined and Helpful)** contributes its equity-relevant guidance to Fairness (responsive/form-factor equivalence, forms cognitive load, and deliberate in-app guidance).
