按照官方教程进行升级操作
确保 PVE 所有节点全部升级至 v8 的最新版本 PVE 8.4.1
升级前务必准备好备份并确保 PVE 中所有 VM 的备份，备份至外部存储，避免可能出现的意外
升级前执行 pve8to9 脚本，使用此官方脚本可以提供有关潜在问题的提示和警告
执行 pve8to9 清单脚本
执行 pve8to9 --full 如下

apt update更新至 Debian 13 同 PVE 9
apt dist-upgrade升级过程中，系统会要求对一些配置文件进行更改
/etc/issue --> N 默认选择否
/etc/lvm/lvm.conf -->Y 默认选择为否，但建议选择为是
Configuration file '/etc/lvm/lvm.conf'
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** lvm.conf (Y/I/N/O/D/Z) [default=N] ? Y
Installing new version of config file /etc/lvm/lvm.conf ...
Installing new version of config file /etc/lvm/lvmlocal.conf ...
Installing new version of config file /etc/lvm/profile/vdo-small.profile .../etc/ssh/sshd_config --> N 默认选择为否，同往常升级一样不要选择为是，避免 sshd 配置更改后无法通过 SSH 进行连接
/etc/default/grub --> N 默认选择为否，保留当前安装的版本
检查更新结果并重新启动至最新内核
更新结束后使用 pveversion 检查版本
root@pve:~# pveversion
pve-manager/9.0.3/025864202ebb6109 (running kernel: 6.14.8-2-pve)然后 reboot 重新启动系统以更新至最新内核
