Best strategy for OS upgradation?
We want to upgrade OS of our 24 node cluster by replicating it to different servers with robust disks updated OS.
Os team suggested since the new disks are much robust then the current ones , so we should replicate this 24 node cluster to a 15 node cluster. We have around 10k objects and 20 TB data to replicate.
What can be the best strategy to follow from docs?
