As the server is running right now, you can update node by node to a elassandra installation with deactivated elastic.由于服务器现在正在运行，您可以逐个节点更新到具有停用弹性的 elassandra 安装。
Once all nodes are updated, you restart one by one and activate elastic.一旦所有节点都更新完毕，你就一一重启并激活elastic。
In case you have only one server running, you should rethink your architecture如果您只有一台服务器在运行，您应该重新考虑您的架构
