我有一台 CentOS 7.9 服务器，主要运行 ZFS 作为 Windows CIF 文件服务器和 NFS vmware 共享。 v7 运行良好。我尝试leapp/elevate进行迁移，但由于NFS而失败，所以我尝试升级到v8，看看是否可以跳转到Alma。
我按照以下步骤操作https://techglimpse.com/how-to-upgrade-centos-7-to-centos-8-linux/这个命令失败了：
dnf -y --releasever=8 --allowerasing --setopt=deltarpm=false distro-sync
有一堆依赖错误。
但
cat /etc/redhat-release显示CentOS Linux release 8.5.2111.- 内核仍然是
3.10.0-1160.90.1.el7.x86_64
运行dnf update表示它将安装 98 个软件包，更新 746 个软件包，并跳过 255 个软件包。但它失败了：
Running transaction check
Transaction check succeeded.
Running transaction test
The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing `dnf clean packages`.

几年前，CentOS 转变为CentOS 流，以及版本 8溪流生命周期结束日期为 2024 年 5 月 31 日，距此还有不到一年的时间！
洛基LinuxCentOS以前是这样的溪流，其 v8 EOL 日期为 5/31/2029。
虽然他们的下载页面没有注明 8.x 版本号，Rocky-8.8-x86_64-dvd1.iso但当前下载的是 11.7gb，如果您不想要版本 9，您可以选择该版本。

迁移数据、重新格式化操作系统磁盘、全新安装Rocky-8.8-x86_64-dvd1.iso、移回数据、安装所需的内容。
