升级nacos从1.4.1到2.3.2

背景：

本月MSE生产环境提示nacos即将过期，阿里云将不维护，故决定对本地测试环境的nacos服务端进行升级,升级至MSE维护最新版2.3.2进行系统兼容性测试。
测试环境的nacos部署在阿里云ack，数据（/home/nacos/data）、日志（/home/nacos/logs）目录进行了持久化配置。

问题现象：

镜像升级至2.3.2之后，发现nacos无法启动。日志显示

原因：

由于目录进行挂载，导致升级后的2.3.2的镜像读取到了1.4.1的数据目录，而这两个版本的数据目录不兼容。

解决思路：

把目录挂载至新的PVC。

注意事项

nacos1.4.1升级至nacos2.3.2会数据库会多一个字段：encrypted_data_key
config_info、his_config_info与config_info_beta新增此字段
字段描述：
 `encrypted_data_key` text NOT NULL COMMENT '密钥'

nacos升级至2.3.2的时候，nacos的加密方式会发生改变，要修改配置文件里的key
