You can upgrade these attributes as new versions of Consul become available or as your networking needs evolve. Note that HashiCorp automatically updates your Consul clusters to fix common vulnerabilities and exposures (CVE). You cannot modify the cluster name, tier, or HashiCorp virtual network (HVN) after creating a cluster.
