如何迁移Fedora目录服务器

Question

我正在尝试将一台旧的Fedora 8机器迁移到CentOS 7，它运行Samba和服务器。它用于验证Windows用户。我想搬到Samba4。做这件事最好的方法是什么？

我尝试过从旧实例导出带有userRoot和NetscapeRoot的db2ldif，然后将它们导入到新系统上的一个新的389-DS基础安装中。然而，当我尝试导入时，似乎什么都没有发生：

[root@localhost ~]# ldif2db -n userRoot -i /tmp/master-fds-vm-userRoot-2019_09_24_143444.ldif -V

如何找出所需的模式等？

Answer 1

389关于升级等基本知识的文档相当稀少，因为它们依赖于。在不同的版本号上。即使所有的混乱，红帽DS文档有关升级从早期版本(7?)可能有用。

关于模式，迁移前的任务包括对架构文件进行复制。。

如果您有一个现有的安装，yum upgrade和setup-ds-admin.pl -u 应该足够了。然而，Fedora 8上的Fedora DS与CentOS 7上的389有很大的差异。导出和导入应该是能够处理版本差异的最兼容的选项。复制可能不是此升级的一个选项。
