Hi,
I have to migrate from ES2.1 to ES6.4. I have an index with ~450 million documents.
Could anyone give me a hint on how to do it ?
Many thanks

Hey,
you cannot directly upgrade to 6.4, as the data cannot be read due to two major version upgrades (2.x to 5.x to 6.x). Also there are breaking changes in between that you need to cater for.
You basically have two possibilities.
