# Migrate content management to v5

> Upgrade document retrieval, resource lists, and document or memory deletion

## Migration details

v5 retrieves, lists, and removes content within one explicit namespace.

### Retrieve a document and its derived context

<CodeGroup>
  ```bash Legacy theme={null}
  GET /v3/documents/{id}
  GET /v3/documents/{id}/chunks
  ```

  ```bash v5 theme={null}
  GET /ns/{namespace}/document/{id}?include=chunks,memories
  ```
</CodeGroup>

Pass `include` as a comma-separated list to return chunks, memories, or both. Keys you omit are absent; requested keys with no results are empty arrays. Lifecycle fields move under `system`:

```json theme={null}
{"system":{"status":"done","createdAt":"...","updatedAt":"..."}}
```

### List documents, chunks, or memories

<CodeGroup>
  ```bash Legacy theme={null}
  POST /v3/documents/list
  POST /v4/memories/list
  ```

  ```bash v5 theme={null}
  POST /ns/{namespace}/list/{type}?page=1&limit=100&sort=createdAt&order=desc
  {}
  ```
</CodeGroup>

Set `type` to `documents`, `chunks`, or `memories`. Pagination and sorting move to the query string; the body contains only optional `filter`.

Every response contains `documents`, `chunks`, `memories`, and `pagination`. Only the selected resource array is populated. Replace legacy `memories` assumptions in document-list callers with `documents`.

### Delete documents

<CodeGroup>
  ```bash Legacy theme={null}
  DELETE /v3/documents/{id}
  DELETE /v3/documents/bulk
  ```

  ```bash v5 theme={null}
  DELETE /ns/{namespace}/document
  {"ids":["doc_1","external_id_2"]}
  ```
</CodeGroup>

The v5 array accepts 1–100 Supermemory or caller-defined IDs. Inspect both `deletedCount` and per-ID `errors`; HTTP success can include partial failures.

### Forget memories

| Legacy intent | v5 operation |
| - | - |
| Forget exact IDs | `DELETE /ns/{namespace}/memories` with `{ "ids": [...] }` |
| Find memories by meaning | `DELETE /ns/{namespace}/memories/semantic` with `{ "query": "...", "dryRun": true }` |

Both return `{ count, matches, errors }`. For drift-free semantic deletion, preview with `dryRun: true`, review the IDs, then submit them to the exact-ID endpoint.

See [memory forgetting](./api-v5-memory-forgetting) for the complete dry-run, approval, response, and audit workflow.

### Verification

* Assert requested empty includes are `[]`, while omitted includes are absent.
* Paginate each resource type until `currentPage >= totalPages`; unselected arrays stay empty.
* Verify chunk rows contain their parent `documentId`.
* Exercise partial document-delete failures and semantic dry runs.
* Verify IDs cannot read, list, or delete content outside their namespace.
