Hello,  
I have to update an ILM and update link to an existing index but i have a doubt on my API call  
Is that good one?  
curl -u elastic:xxxx -k -X PUT "[https://elasticsearch-1:9200/index-raw-syslog/settings?pretty](https://elasticsearch-1:9200/index-raw-syslog/settings?pretty)" -H 'Content-Type: application/json' -d '{ "index": { "lifeycle": {"name": "raw-syslog","rollover\_alias:"raw\_syslog" } } } '

Thank you
