将Corda节点从CE3.2升级到CE4.0，并遵循以下文档步骤：

运行ubuntu@ip-xyz:~$ java -jar tools-database-manager-4.0.jar dry-run -b /opt/corda/

给出错误：

我已经安装了驱动程序，插件和cordapps所需的所有文件夹，并安装了MS SQL驱动程序mssql-jdbc-6.2.2.jre8.jar。

Answer 1

node.conf中的"jarDirs"键隐藏了数据库迁移所需的文件夹。

通过删除以下几行，数据库管理器工具成功完成了空运行。

    "jarDirs" : [
        "plugins",
        "cordapps"
    ]
