  title: Slack Migration Exchange API
  description: Slacks Migration API is a Web API used during Enterprise Grid migrations to translate legacy, workspace-scoped identifiers into their new, canonical IDs so apps keep working after a workspace moves or merges. By calling its migration.exchange method, developers and admins can map old user and channel IDs to the new values that Slack assigns in an Enterprise Grid org, allowing databases, webhooks, event subscriptions, and app configurations to be updated without losing references. It complements Admin and SCIM APIs in a migration runbook, but it doesnt move content or provision accountsit strictly provides ID remapping to preserve continuity.
