Rename an index

Hey

Is there a way to rename (or copy) an index from the APIs ? -- not an
alias.

Thanks
Tarek

To my knowledge, there is no "rename" or "copy" API.

For copy, you can search for scroll and scan API to iterate over all docs
and index them in a new index.

A better option would be to maintain aliases -

Yeah I will try that. It sounds suboptimal though, maybe I should post a
feature request.

That's what we do now - but I have an existing instance with some indexes I
wanted to copy over.

Ah, you can import dangling indices into a cluster. The problem is when
they have the same name as existing indices.

I opened this issue about exactly that problem:

github.com/elastic/elasticsearch

Importing a renamed index

If I copy the directory that contains an index to a new directory name, then res…tart the cluster, I see the message: ``` [INFO ][gateway.local.state.meta ] [Sytsevich, Aleksei] dangled index directory name is [new_name], state name is [old_name], renaming to directory name ``` This, to me, implies that the state name is being changed to the directory name. In other words, I should have a new index called `new_name`. Actually, it just ignores the index because we already have `old_name`. If I edit the state file to change the state name, then I get a new index with the edited name. So first: the log message is inaccurate. It should be "renaming to state name". But second, I think the better behaviour would be to update the state name to the directory name. For one, this would make it easy to physically rename an index.
