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

-H "Authorization: Bearer zdk_live_…"Signed in? The API console in your dashboard fills in your real organisation id and your own key, and runs the request against the live API so you can see the actual response. Open this endpoint in the API console
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 reachable… |
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: a… |
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… |
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 faithfully… |
replaces_existing | boolean | No | Whether this migration landed on a site that already held a website. Stamped when the job is created and never recomputed: after the apply step the site is occupied… |
safety_backup_state | string<not_needed, pending, taken, unsupported, failed> | No | What became of the backup taken immediately before the apply step replaced the site. ⛔ Five values rather than a boolean: "there is no safety backup" is one rendered sentence… |
safety_backup_id | string | No | The SiteBackup id, or "". ⛔ Still reported after the archive has been pruned by retention, so a rollback can say "that archive has expired" rather than looking like a… |
rolled_back_at | string | No | When the customer put the site back. Set once — restoring the pre-migration archive over a site that is already the pre-migration archive can only lose work done since. |
rollback | MigrationRollback | No | Whether this migration can be put back, and — when it cannot — why not. ⛔⛔ reason travels with available, always. Six different facts render as the same absent button… |
started_at | string | No | — |
finished_at | string | No | — |
created_at | string | Yes | — |
