Answer 1

You might use a shift transformation which contains two conditionals

• whether outermost attribute is "destSiteName" or not ( "*" )

or

• whether value of "destSiteName" is "unknown" or not ( "*" )

[
  {
    "operation": "shift",
    "spec": {
      "destSiteName": {
        "unknown": "",
        "*": { "@1": "&2" }
      },
      "*": "&"
    }
  }
]
