I newly created an index templates that has the following index-pattern log-*, And i already have an old index under the name log-server which has a timestamp field that contains a different format than the default formats in elasticsearch ,which is yyyy-MM-dd HH:mm:ss,SSS , so i have put this form…

Index templates are applied at index creation so will not apply to already existing indices.

Newly created index template does not apply on old indices?

Thank you ,
I just wanted to validate my assumption ,so sorry if it was a plain question.
So does that mean that i have to delete my index and create a new one and if yes, how can i backup my data inside that index and re-emit them to the new one ?
