How to migrate index into other machine

Elastic Stack Elasticsearch
1

Hi.
I have two machines, in the first I have indexes that I want migrate them to the second machine, but in the second machine I have some indexes that I don't want lose them.

I had proved to copy the indices folder but kibana doesn't show them.
I also try snapshot but can't restore because kibana_task_manager already exist.

There are another way or idea that I can prove it?

Regards.

Solved.

I have loaded the snapshots specifying indexes one by one.

POST /_snapshot/my_backup/snapshot-one/_restore
{
 "indices":"indexname"
}

I have used this guide:

https://www.elastic.co/guide/en/elasticsearch/reference/7.3/modules-snapshots.html

But i dont know if is the best way to do it.
