Explanation

Using multiple schedulers to upgrade different update groups on different evenings allows you to spread the maintenance over the 15-day window while controlling downtime. Dividing the 200 nodes into multiple odd/even update groups with up to about 10 nodes each limits the blast radius of each maintenance window and supports a rolling upgrade with minimal
