POST /v1/sites/{siteId}/migrations/{migrationId}/cutover
Re-sync the mail that arrived during the move.
Authentication
Send an API key as a bearer token. The key must carry the hosting.import.manage permission; a key without it is refused with 403, not 404.
This endpoint takes no organisation id. Your key already identifies the organisation it belongs to, and the response is scoped to it.

Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.

Details
Runs the **mail delta**, and it is the control that makes mail survive a migration. Mail keeps arriving at the old host while we copy, so the sequence is: full sync → the customer moves their MX → this. The delta asks the source only for messages above each mailbox's high-water UID, which is what stops a second pass duplicating an inbox. Only a job in `awaiting_cutover` may be cut over (422 `migration_not_awaiting_cutover` otherwise): running it earlier would re-read the whole estate, and running it on a finished job would reopen a session on a server the customer may already have cancelled. A website-only migration is **refused** rather than accepted as a no-op (422 `migration_has_no_mail`) — a control that reports success and does nothing is how a customer concludes their mail moved when it did not. Requires `hosting.import.manage`.
Parameters
| Name | Type | Required | What it is |
|---|---|---|---|
siteId (path) | Uuid | Yes | Site ID (UUIDv7). |
migrationId (path) | Uuid | Yes | The migration job's id (UUIDv7), as `listSiteMigrations` reports it. **Ours**, minted when the row was written — never anything the source host knows about. |
Response
| Name | Type | Required | What it is |
|---|---|---|---|
id | Uuid | Yes | UUIDv7 identifier — sortable by creation time (docs/02 §8). |
site_id | Uuid | Yes | UUIDv7 identifier — sortable by creation time (docs/02 §8). |
source | MigrationSource | Yes | The kind of hosting the site is being pulled from. ⛔ `plesk` is offered so the refusal can be specific and actionable, **not** because it is supported: `pleskbackup` is reachabl… |
status | SiteMigrationStatus | Yes | `authenticating`, `inventorying` and `transferring` are separate states rather than one `running` because they fail for opposite reasons and the customer's next action differs:… |
status_reason | string | No | A machine code the dashboard renders through its own catalogue — never an English sentence composed by the engine, which could be shown to none of the other 57 locales. |
include_mail | boolean | Yes | — |
source_host | string | No | The hostname the estate is being pulled from. Host only: no port, no username, and never a secret. |
files_total | integer | Yes | — |
files_done | integer | Yes | — |
databases_total | integer | Yes | — |
databases_done | integer | Yes | — |
mailboxes_total | integer | Yes | — |
mailboxes_done | integer | Yes | — |
items_failed | integer | Yes | ⛔ Counted separately from the `*_done` fields, never folded into them. "We could not get it" reported as "done" makes the completion report a lie. |
bytes_transferred | integer | Yes | — |
warnings | string[] | Yes | Machine warning codes the dashboard localises. |
mail_synced_at | string | No | When the mail delta last ran. `null` and a timestamp are different states, and the cutover control reads this to tell them apart. |
dns_records_captured | integer | No | How many records were read off the source's zone and will be published on cutover. ⛔ Counted separately from `dns_records_unsupported`, never as one total: "we captured 14 recor… |
dns_records_unsupported | integer | No | Real records the source holds that our DNS editor cannot express (an `SSHFP`, a `TLSA`, an `MX` with no preference). Stored and listed on the detail endpoint rather than dropped… |
dns_captured_at | string | No | When the source's zone was read. `null` means never attempted, which is NOT the same as attempted-and-the-panel-holds-no-zone; only the first is worth retrying. |
verified_at | string | No | When the migrated site was last fetched over HTTP and compared with the source. `null` means the destination has never been looked at. |
verification_code | string | No | A machine code the dashboard localises. Empty means the destination is serving the site as well as the source was. ⛔ The migration's own counters cannot answer this: they travel… |
destination_status | integer | No | The HTTP status the migrated site returned, fetched at its origin address with a `Host:` header — before cutover the customer's domain still resolves to the OLD host, so asking… |
source_status | integer | No | The HTTP status the source returned. ⭐ Reported beside `destination_status` because the interesting failure is the PAIR: a destination 200 against a source 500 means we faithful… |

finished_at | string | No | — |
created_at | string | Yes | — |
