type: "durable-object"

Marks this entry as a Durable Object export.

WorkersDurableObjectRenamedExport object { renamed_to, state, type }

A renamed tombstone: rewrites the provisioned namespaces class name from this map key to renamed_to. The source class may stay in code during the rollout window (an info notice is emitted). storage, transferred_to and transfer_from are not allowed.

Tombstone that renames the namespaces class.

type: "durable-object"

Marks this entry as a Durable Object export.

WorkersDurableObjectTransferredExport object { state, transferred_to, type }

state: "transferred"

Tombstone that transfers the namespace to another script.

transferred_to: string

The destination script name. Must be in the same account and the same dispatch-namespace context (or both non-dispatch). Cross-dispatch-namespace transfers are rejected. Write-only: never present in GET responses.

state: "expecting-transfer"

Target side of a two-phase transfer.

storage: "sqlite" or "legacy-kv"

One of the following:
