Hi All,
We have an ELK 6.8.6 running in K8 cluster and looking forward to upgrade it to Open Distro 1.3.0.
After reading through the docs it seems installing Open Distro as a new cluster is easy but not much information is available to upgrade the existing cluster which is using PVCs.
Has any one tried upgrading ELK in K8 cluster to Open Distro attaching it to the existing PVCs and not losing any data?
Thanks in advance.
