Reindex data stream

Elastic Stack Elasticsearch

Hello,

There is conflicts with fields in the data stream backing indices. I would like to know the correct way to resolve this issue. While reindexing data is possible with regular indexes, I am unsure how to proceed with data streams. Could you please provide guidance on how to address this? Thank you.

It is in the documentation.

You need to point to the data stream name, with the op_type set to create and then data will be written to the current backing indice.

If you changed mappings on your template I think you will probably need to force a rollover before.
