Remount ( API )

The Remount documentation details the endpoints required to trigger and monitor the status of a remount operation.

Move Backend

The /sys/remount endpoint moves an already-mounted backend to a new mount point. This process works for both secret engines and auth methods.

The remount operation returns a migration ID to the user. The user may utlizie the migration ID to look up the status of the mount migration. More details about the remount operation are described in Mount Migration.

Note: This endpoint requires a policy with both sudo and update capabilities to sys/remount

Note: A mount migration will revoke all leases for the secrets of a secrets backend or tokens of an auth backend, depending on which type of backend is being moved.

Method	Path
`POST`	`/sys/remount`

Parameters

from (string: <required>) – Specifies the previous mount point.
to (string: <required>) – Specifies the new destination mount point.
