So I have inherited a mix of versions - 3.3.21 (!), 3.6.3, and 3.11.02.
I want to get to 3.13 at a minimum and update the protocol.
Reading through the notes I see monitoring changes in 3.9 (https://www.aerospike.com/docs/operations/upgrade/stats_to_3_9) and network changes in 3.10 (https://www.aerospike.com/docs/operations/upgrade/network_to_3_10). As long as I change the config file as I go, can I do a rolling upgrade straight to 3.13?
I realize I need to get each cluster up to 3.13 before changing the protocol.
