We are trying to upgrade elastic server from 6.8.5 to 7.5.2. Now our micro services are using elasticsearch-rest-high-level-client version 6.8.13. We don't see any problems in communication between elastic server 7.5.2 and elasticsearch-rest-high-level-client-6.8.13.
In maven dependency tree I can see internally elasticsearch-rest-high-level-client-6.8.13 using elasticsearch-6.8.13 & elasticsearch-rest-client-6.8.13.
Question is, elasticsearch-rest-high-level-client-6.8.13 compatible with elastic server 7.5.2 ? Can I go ahead for production with elasticsearch-rest-high-level-client-6.8.13.
