# Create pool transfer

`POST /preview/v2/pool_transfers`

> ⚠️ This endpoint is in [public preview](/preview/roadmap).

Transfer some or all of one pool into another

## Headers

- `Idempotency-Key` string, nullable

## Request body

- V2CreatePoolTransferRequest — Transfer some or all of one pool into another.
  - `from_pool` string, required — A resource path like 'sfc:pool:acme:prod:my-pool' _or_ an ID. Resource paths are human-readable but not stable - they change when resources are renamed or moved. IDs are stable and permanent.
  - `to_pool` string, required — A resource path like 'sfc:pool:acme:prod:my-pool' _or_ an ID. Resource paths are human-readable but not stable - they change when resources are renamed or moved. IDs are stable and permanent.
  - `allocation_schedule_delta` ScheduleEntry[], required — Node count over time, as a list of `[start_at, end_at)` time ranges. Example: 5 nodes from t=0 to t=3600 is `[{"start_at": 0, "end_at": 3600, "node_count": 5}]`. `start_at` and `end_at` must be 60-second aligned, `node_count` must be non-negative. On non-final entries, `end_at` may be omitted (inferred from the next entry's `start_at`); gaps fill with `node_count: 0`.
    - `start_at` integer, required — Unix timestamp.
    - `end_at` integer — Unix timestamp.
    - `node_count` integer, required
  - `instance_sku` union, required — Accepts the canonical prefix below; additional legacy prefixes are aliased for read compatibility. Writes always emit the canonical form.
    - string
    - string — Legacy alias prefix; accepted on read, never emitted on write.

## Response `202`

Pool transfer accepted.

- V2PoolTransferResponse — A transfer of compute from one pool (`from_pool`) to another (`to_pool`).
  - `object` 'pool_transfer', required — Discriminator for `/pool_transfers` responses.
  - `id` union, required — Accepts the canonical prefix below; additional legacy prefixes are aliased for read compatibility. Writes always emit the canonical form.
    - string
    - string — Legacy alias prefix; accepted on read, never emitted on write.
  - `status` 'pending' | 'executed' | 'rejected', required — Lifecycle status of a pool transfer.
  - `created_at` integer, required — Unix timestamp.
  - `from_pool` string, required
  - `to_pool` string, required
  - `instance_sku` InstanceSkuSummary, required — A summary of an instance SKU - its `id` and human-recognizable `alias` - embedded on resources that reference a SKU.
    - `object` 'instance_sku', required
    - `id` union, required — Accepts the canonical prefix below; additional legacy prefixes are aliased for read compatibility. Writes always emit the canonical form.
      - string
      - string — Legacy alias prefix; accepted on read, never emitted on write.
    - `alias` string, required
  - `rejected_reason` string, nullable — Reason a pool transfer was rejected.
  - `allocation_schedule_delta` ScheduleEntry[], required — Node count over time, as a list of `[start_at, end_at)` time ranges. Example: 5 nodes from t=0 to t=3600 is `[{"start_at": 0, "end_at": 3600, "node_count": 5}]`. `start_at` and `end_at` must be 60-second aligned, `node_count` must be non-negative. On non-final entries, `end_at` may be omitted (inferred from the next entry's `start_at`); gaps fill with `node_count: 0`.
    - `start_at` integer, required — Unix timestamp.
    - `end_at` integer — Unix timestamp.
    - `node_count` integer, required
