Editing a host profile results with an error.
In a vCenter Server inventory upgraded to version 6.5 if you try to edit the settings for a host profile with version 5.1, one of the following errors might appear:
Unexpected status code: 503
There are no hosts available in the inventory at the version for the selected Host Profile
vSphere 6.5 supports only hosts and host profiles with version 5.5 and later.
Extract a Host Profile from an already upgraded host to version 5.5. or later.
Use the Copy Settings from Host option to copy the configuration settings from a host already upgraded to a version 5.5. or later.Note:
Using the Copy Settings from Host option overwrites the settings within the existing Host Profile or sets them to the default values.
