Elasticsearch-dsl (python) migration from ES 2.3 - 6.0

Hi there,

I am in the early stages of scoping out our migration from ES 2.3 to ES 6.
The remote-reindex feature seems to be the path we will take to migrate our actual data.
We have a fairly extensive collection of queries that use the python elasticsearch-dsl. Looking for some advice (and also potential gotchyas) on migrating DSLs.
Is there an available document of breaking changes between these versions of ES that the dsl itself can handle and things that it won't handle?

This is a pretty broad question but appreciate the help!



I'm not aware of such a document but the changelog of elasticsearch-dsl might be helpful.
