Hi,

I ran into kibana mapping conflict issue after updating data types for some fields.
The only option i have is to reindex the old data to resolve this issue.
We have hourly indices with 30 days of data.
Can you please suggest best way to automate the process.

Take a look at the reindex API in combination with an index template that has your field mapped properly.
