Hi, in my index template "clientip" field is text. so I need to reindex the indices.  
It's been about 2 months and indices are create every day:

> logstash-vod-2020.04.14  
> logstash-vod-2020.04.13

In docs I see I should use something like this:

> POST \_reindex  
> {  
> "source": {  
> "index": "twitter"  
> },  
> "dest": {  
> "index": "new\_twitter",  
> }  
> }

How can I write some loop or script that takes the dates and starts to reindex ?  
How can I change only "clientip" data type from text to ip ?  
It's my first time in ES reindex, I guess this "dest" index is kind of temp and I should change the name of it to what is was before. I mean logstash-vod-2020.04.14 will reindex to logstash-vod-2020.04.14\_new, logstash-vod-2020.04.14 will be deleted, logstash-vod-2020.04.14\_new will renamed to logstash-vod-2020.04.14. Am I right ?  
That was a long question, thank you so much 😅
