As I looked into Couchbase upgrade without cluster down.
There is two ways to do that
1- Swap rebalance
2- Standard online upgrades
I found that Swap rebalance way is better than Standard online because it will not down the cluster performance.
Can I directly update Couchbase from 1.8.x to 3.x directly , If no then please share the steps to do that?
Thanks in Advance.
