Recovery Snapshot from ES1.7.3 on ES.2.2.0

Elastic Stack Elasticsearch

Hi,

I try recovery snapshot index of ES 1.7.3 in ES 2.2.0 but when I restart the 2.2.0 cluster the recovery indexes become red.

There's a way to resolve this?

I don't think you can do it if your indices are not compatible with 2.x version.
The only way to know that IMO is to use the migration plugin on your "old" cluster.
