That's unusual from my perspective. Where is the time being spent? And what versions are you using?
We have over 20 clusters between 3-9 brokers each, and I do rolling upgrades across all of them in an hour or two with the main delay being keeping an eye on client performance. I can push through one in 15 minutes if I'm particularly in a rush. They're production clusters, thousands of partitions each, about 20 billion messages / day, TBs of data on each broker.
