Just moved to Elastic Cloud from on-onprem for our logging, setting up data streams instead of using date based indices. I now need to restore our historical data from snapshots - anyway to restore these into the data stream format?

You can't directly do that, as datastreams expect the data to be indexed in.

[Set up a data stream | Elasticsearch Guide [8.2] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/8.2/set-up-a-data-stream.html#convert-index-alias-to-data-stream) might work if you were using aliases previously.

Maybe [the modify data stream api](https://www.elastic.co/guide/en/elasticsearch/reference/8.2/modify-data-streams-api.html) may also help here. If you already have a data stream and you just like to add some restored indices to it then this should work. These indices will need to have a `@timestamp` field, otherwise it will not be possible to add these indices to a data stream.
