I see the handy the migration plugin with two options: 1 for upgrading from 1.x to 2.x and one for upgrading from 2.x to 5.x. Is there an option for 1.x to 5.x?
Asking because we're currently running elasticsearch 1.7 and plan on moving straight to 5.0 (rather than upgrading to 2.x then to 5) by standing up a new cluster and then using the reindex from remote option to reindex our lucene version 4 indices.
Thanks for the quick reply! If our approach is to standup a 5.0 cluster, regarding the approach to migrating data, does elastic recommend a) restoring snapshots from 1.7 or b) reindex from remote?
