Hello,

I was just wondering if it is possible to migrate older data to slower media, possibly using "curator."

Basically, I want the most current data on the fast SSDs, then as the data gets older, I want it moved down to our slower HDDs, then eventually to offline storage. It seems like something that folks would want to be able to do. I looked into this a while ago and was told that I would have to somehow utilize separate ES instances for each level of storage: one pointed at the SSDs, one for the HDDs, etc.

Even if I have to close an index before moving it to HDD, that'd be ok.

Anyone doing anything like this?

Thanks.

I think [Hot/Warm Architecture](https://www.elastic.co/blog/hot-warm-architecture-in-elasticsearch-5-x) is what you're after?

Indeed. You can migrate to _nodes_ with slower HDDs, but not on the same box, unless you happen to have multiple nodes with different data paths on the same physical machine.
