This is independent of enabled. It can stay true while caching is off, so the preference survives turning caching off and back on. Link to this property

Storage ScriptUpdateParamsMetadataExportsWorkersDurableObjectExportStorage Durable Object storage backend. sqlite is the recommended (and only) backend for new namespaces. legacy-kv is accepted only for a class whose namespace already exists as KV-backed; the exports flow never provisions a new legacy-kv namespace.

type ScriptUpdateParamsMetadataExportsWorkersDurableObjectRenamedExport struct{…} A renamed tombstone: rewrites the provisioned namespace’s 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.

RenamedTo string The destination class name. Must differ from the source class (the map key) and must be declared as a live (created) entry in the same exports map.

Link to this property Type ScriptUpdateParamsMetadataExportsWorkersDurableObjectRenamedExportType Marks this entry as a Durable Object export. Link to this property

Link to this property

type ScriptUpdateParamsMetadataExportsWorkersDurableObjectTransferredExport struct{…} A transferred tombstone (source side of a two-phase transfer): hands ownership of the provisioned namespace to another script in the same account, named by transferred_to. The target must have already deployed a matching expecting-transfer entry. The source class may stay in code during the rollout window (an info notice is emitted). storage, renamed_to and transfer_from are not allowed.

State ScriptUpdateParamsMetadataExportsWorkersDurableObjectTransferredExportState Tombstone that transfers the namespace to another script. Link to this property TransferredTo string The destination script name. Must be in the same account and the same dispatch-namespace context (or both non-dispatch).

Link to this property

type ScriptUpdateParamsMetadataExportsWorkersDurableObjectExpectingTransferExport struct{…} The target side of a two-phase transfer (state: expecting-transfer). Declares that this script expects to receive a namespace for this class from the transfer_from script. This is a live entry, not a tombstone: bindings resolve through the source’s namespace until the source commits with a transferred tombstone. storage and transfer_from are required; renamed_to and transferred_to are not allowed.

State ScriptUpdateParamsMetadataExportsWorkersDurableObjectExpectingTransferExportState Target side of a two-phase transfer. Link to this property

Storage ScriptUpdateParamsMetadataExportsWorkersDurableObjectExpectingTransferExportStorage Durable Object storage backend. sqlite is the recommended (and only) backend for new namespaces. legacy-kv is accepted only for a class whose namespace already exists as KV-backed; the exports flow never provisions a new legacy-kv namespace.
