Migration Center

The Migration Center API is the preferred mechanism to migrate legacy content to the Arc XP platform. This API provides a RESTful interface for customers to load Arc XP Native Specification (ANS) documents at scale without concerning themselves with Draft API-imposed rate limits.

Base URL: `https://api.{org}.arcpublishing.com/migrations/v3/...`

This API is subject to rate limits, as noted in the [Service SLA section of this article](https://dev.arcxp.com/migration-center/developer-docs/migration-center-30-new-features-and-key-changes/#service-slas). This API requires an access token, which is managed within Developer Center. [Learn more about working with access tokens here](https://dev.arcxp.com/api/accessing-arcxp-apis/).
