I'm trying to convert a field that is a keyword to a long but I cannot edit it, it is fixed in the transform index.

So I tried to use a ingest node pipeline which use convert keyword to long but how do I use that ingest node pipeline to my transform index?

For example the original index pattern has type like this:

time type: text,long  
time.keyword type: keyword

then when I transform the index I dont have the option to make it a a time.long or long so it has to be a keyword, then in the transform index pattern I cannot change it to a long

Is there a way to change it to a long or a number?

You can set the settings and mappings of the desitnation index beforehand.  
Below is the description about destination index parameter of transform API.

> `index`
> 
> (Required, string) The _destination index_ for the transform. The mappings of the destination index are deduced based on the source fields when possible. If alternate mappings are required, use the [Create index API](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-create-index.html) prior to starting the transform.
