We use the official Dgraph Chart (an older version which was copied from https://github.com/dgraph-io/dgraph/tree/master/contrib/config/kubernetes/helm) and we have 3 Alphas, 3 Zeros - all the same configuration in three clusters, below is our values.yaml.

Does using an older Chart can be a problem?
