Still about scaling/sizing…but not about bandwith. If in a few months, i want to upgrade my 3 current nodes (2 vCPUs , 2 GB) to 3 nodes of another configuration (8vCPU, 32 GB, SSD drives).
Can i use the same method as described in your documentation : Online upgrade with swap rebalance ?
http://docs.couchbase.com/admin/admin/Install/upgrade-online.html
So basically add 1 of the new servers to my cluster, put all the data on it, remove the 3 olds nodes from the cluster, then add the 2 others “new” servers to the cluster.
If yes, can i do this if my 3 old servers are under Couchbase 3.0 and the new under 4.0 ?
