# at.happyproto.server.upgradeInstance

> Upgrade one of the caller's instances to the newer HappyView release its availableVersion offers, and start a job that follows the upgrade. The instance is offline for about 30 seconds; its database is snapshotted first, and a release that does not come up healthy is rolled back. Customers only.

## Procedure (`at.happyproto.server.upgradeInstance`)

Type: procedure · POST

### Input (application/json)

- `id` (string, required): The instance's UUID.
- `idempotencyKey` (string, required): A UUID the client generates once per intended change and resends on every retry of it, so a retry gets the original reply instead of acting twice.
- `version` (string, required): The release to upgrade to: the instance's availableVersion.version, as the caller was shown it.

### Output (application/json)

- `jobId` (string, required): The background job following the change. Poll it with at.happyproto.server.getJob.

### Errors

- `AuthRequired`: This endpoint requires an authenticated caller.
- `Forbidden`: The caller is not a HappyProto customer, or the provisioner refused them.
- `InvalidRequest`: id or idempotencyKey is missing or not a UUID, version is missing, or the release is not newer than the one the instance runs.
- `NotFound`: No such instance, or it is not the caller's. The two are indistinguishable.
- `InvalidSlug`: Passed through from the provisioner: it reserves slugs by configuration as well.
- `SlugTaken`: Passed through from the provisioner.
- `NotEntitled`: Passed through from the provisioner.
- `InstanceLimit`: Passed through from the provisioner.
- `NoCapacity`: Passed through from the provisioner.
- `OperationInProgress`: Passed through from the provisioner: the instance is already changing, or a request with this idempotencyKey is still running.
- `UpgradeUnavailable`: The release is not the one on offer for this instance: there is none, a newer one replaced it, or the instance already runs it.
- `Upstream`: The provisioner is unreachable, not configured, or answered with an error it does not explain to callers, or the job could not be started.
