Clarify high level REST client compatibility between 6 and 7

I have traffic coming in constantly in my application and I need to migrate from ES6 to 7. According to the doc the client should be migrated last. But will a client 6 work with a cluster in version 7? How this should be handled? I am surprised the migration guide does not mention this, I must be missing something obvious.

As long as you are not using any deprecated features you should be able to use the v6 REST client against the v7 cluster. The deprecation logger and the upgrade assistant will help you find whether you're using any deprecated features. Make sure to run the latest v6.8 release to get the most up-to-date implementation of the upgrade assistant.
