migrate form version 6.X to 7.X ?

[guldil]

Hello

We currently use elastica bundle in a Symfony 4.4 application with an ElasticSEach 6.8 cluster.
We want to upgrade to ElasticSearch Cluster 7.X.

Do we have to be synchronous to migrate between the two major versions?

Is it possible to use a 7.X version of the Elastica bundle to an ElasticSearch 6.8?

Thanks

Guldil

Unfortunately the answer is it depends. In many cases, it will just work, but it depends a bit on what deprecated features you use in 6.x and if some specific features that got removed in 7.x you use. I recommend you to have a very detailed look at the breaking changes in https://github.com/ruflin/Elastica/blob/master/CHANGELOG.md for all the 7.x releases.

If you have a chance of a snapshot or staging deployment to test this?

Thanks @ruflin we'll try this :)
