I changed the first solution (we were referring to) to be:

```
mutate
{
  convert => { "acme.date" => "string" }
}

```

and it still does not convert `acme.date` from type `date` to `string` which strikes me as very odd since `mutate`/`convert` is documented as a working feature. It seems pointless to have such a feature if it doesn't work (which is my backward way of asking, rhetorically, why it does not). Clearly, the `dissect` clause is doing its job perfectly.

Note that, however unrelated and irrelevant, `remove_field` works:

```
filter
{
  dissect
  {
    mapping =>
    {
      "message" => "%{acme.date} %{acme.time} CEF:%{acme.version}|%{acme.device_vendor}|%{acme.device_product}|%{acme.device_version}|%{acme.device_event_class_id}|%{acme.name}|%{acme.severity}|%{acme.extensions}"
    }
    remove_field => ["message"]
  }
}

```

This removes the superfluous `message` field after the new, split-out fields have been created.
