如何升级 Milvus 单机版本 v2.1.4 to v2.2.0

[bluestaree]

按照官方文档步骤走： (https://milvus.io/docs/upgrade_milvus_standalone-docker.md)

在执行第三步命令时，控制台打印如下信息：

[2022/12/16 08:09:33.302 +00:00] [DEBUG] [sessionutil/session_util.go:185] ["Session try to connect to etcd"]

是否需要其他配置？

访问不到etcd了，那个migration需要访问etcd去更新里面的内容，docker ps看一下etcd还在否，如果etcd还在运行，那么检查一下ip/port对不对得上
