Master/ETCD Migration



Hello, i have to migrate my production HA masters/etcd servers to new boxes.

Steps Intended:

1) Create a new masters and etcd machines using byo/config playbook.
2) Stop the old masters and move etcd data directory to new etcd servers
3) Start the new masters
4) Run byo/openshift-cluster/redeploy-certificates.yml against the cluster to updage CA and node configuration.

Question:
- Is it the best or the right way to do since this is a production cluster and i want minimal downtime?
