If the Proxmox VE Node Info check rule was configured in Checkmk 2.4, where the required node status was stored as a plain string (e.g. True) instead of a per-status mapping, the Proxmox VE Node Info service went to UNKNOWN with AttributeError: 'str' object has no attribute 'get' on every check run after upgrading to 2.5.

The parameter migration now converts any such legacy string value to the default status mapping, so the service continues to report the node status without error.
