# migratePortShape

[Source](https://github.com/konoe-akitoshi/shumoku/blob/main/libs/@shumoku/core/src/models/migrate.ts#L42)

Backwards-compat shim for saved files: an older NodePort serialized with \`cage: PortConnector\` (or \`cage: 'combo'\`) is normalized into the modern \`connectors: PortConnector\[\]\` shape on read. Combo expands to \['rj45', 'sfp'\] as a best-effort default; users can refine from the editor afterwards.

```
migratePortShape(port: T): T
```

## Parameters

| Parameter | Type | Description | Default |
| --- | --- | --- | --- |
