What versions of elasticsearch is stream2es compatible with?

[maxrothman]

We're investigating using stream2es to migrate from ES 0.90 to 5.1. Is stream2es compatible with both versions?

[drewr]

Cross-version compat with the es stream hasn't been focused on, unfortunately. There's a chance you could --tee-bulk it with a 0.90-compatible version from that cluster and curl it to the 5.x cluster. GNU parallel makes this fast if you have many cores.

time find /path/to/bulks -name \*.gz \
   | parallel "curl -s -XPOST 5xcluster:9200/_bulk --data-binary @<(gzip -cd {}) >/dev/null"

That doesn't check for bulk errors, but you get the idea.

I also have an error with 5.1:

So I just created the index myself and now I see this:

No search type for [scan]

I know there is a _reindex API now, but this tool is useful when dealing with two separated clusters and it looks like it's not compatible with Elasticsearch 5.
