When I need to migrate SkyWalking data from an old ES cluster to a new ES cluster, I found that the skywalking_segment index in the new ES cluster has no data written. Are there any other configurations that need to be adjusted?

I am not migrating the data from the old Elasticsearch cluster; instead, I want to replace the old ES cluster with a new ES cluster.

I guess you are running on k8s? You should rerun the init job of skywalking helm.
There are index templates should be recreated.

I have already synchronized these templates from the old cluster to the new cluster, but it still cannot write. Metrics data can be written, but only the segment index cannot be written.

There are no difference. Consider to remove the index and index template to do that again

Ok，I‘ll do it
