Consul Enterprise enables the capability of automatically upgrading a cluster of Consul servers to a new
|
|
version as updated server nodes join the cluster. This automated upgrade will spawn a process which monitors the amount of voting members
|
|
currently in a cluster. When an equal amount of new server nodes are joined running the desired version, the lower versioned servers
|
|
will be demoted to non voting members. Demotion of legacy server nodes will not occur until the voting members on the new version match.
|
|
Once this demotion occurs, the previous versioned servers can be removed from the cluster safely.
