Conflicts of OS versions

Elastic Stack Elasticsearch
1

HI all,

We are using elasticsearch 1.3.7 cluster , we are working hardly on upgrading es version.
We are need to add more nodes to cluster for some high performance urgently.
now all ES nodes are running in centos6.7 version , we are planning to add nodes to cluster in centos7 version.

Is there is any possibility for issues in cluster due conflicts of OS versions??

please confirm and help on this.

IIRC this version, one super important thing is to have the exact same JVM (Vendor and Version).

Never heard anything regarding the OS itself.
