Can I create an index with data obtained with bucket aggregation from another index?

For example:

> old\_index: fox; dog; dog; fox; fox;  
> new\_index: fox, 3; dog, 2;

Is it possible to do this for some indexes within ILM?  
And can I delete `old_index` immediately when creating `new_index`?

Take a look at [Rolling up historical data | Elasticsearch Guide [7.17] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/7.17/xpack-rollup.html)
