Upgrade vSEC cluster from R80.30 to R80.40 in AWS
We have a R80.30 cluster in AWS and would like to upgrade it in the near future to R80.40. Is possible to upgrade it via CPUSE directly or does we need to deploy a new cluster from a cloudformation template?
Both members are in same AZ and same VPC.
We have several elastic IPs attached to it to publish services so we would like to have an upgrade with no service interruption if possible.
