Rolling OS6-7 migration for CM-Parcel Installed CDH Cluster

Rolling OS6-7 migration for CM-Parcel Installed CDH Cluster

New Contributor

We are planning an OS migration (CentOS6-7) on production environments with >200 hosts.

For CM managed, parcel installs, I couldn't find knowledge base articles that show a rolling migration approach in place for an up and lift or blue-green migration of hadoop clusters. Is it supported? Blue-green migration would get quiet expensive for the period before we can decommission the old cluster.
