将RHEL版本7.6升级到RHEL 8.4 (脱机)

Question

我们正在努力将我们的RHEL服务器7.6升级到RHEL 8.4

作为

 leapp preupgrade --no-rhsm --enablerepo BaseOS --enablerepo AppStream

但最后我们得到以下错误

============================================================
                     UPGRADE INHIBITED
============================================================

Upgrade has been inhibited due to the following problems:
    1. Inhibitor: The installed OS version is not supported for the in-place upgrade to RHEL 8
    2. Inhibitor: Detected loaded kernel drivers which have been removed in RHEL 8. Upgrade cannot proceed.
    3. Inhibitor: Missing required answers in the answer file
Consult the pre-upgrade report for details and possible remediation.

============================================================
                     UPGRADE INHIBITED
============================================================

知道如何从舞台上继续下去吗？

注意：

在/etc/leapp/files下，我们设置了以下文件

ls -ltr /etc/leapp/files

Answer 1

抑制剂:本地升级到RHEL 8不支持已安装的操作系统版本。

您需要首先(7.9)升级到最新的RHEL 7小版本(7.9)，请参阅支持红帽企业Linux的就地升级路径 (对于不同的体系结构有一些例外，但我认为这些不适用于您，因为您得到了这个错误)。

抑制剂:在应答文件中缺少所需的答案

检查leapp-report.txt中的升级前报告并回答以下问题.有关详细信息，请参阅升级文档第三章对升级前报告进行回顾。。

抑制剂:检测到已在RHEL 8中删除的加载内核驱动程序。升级无法进行。

删除的驱动程序也在升级前报告中。检查哪些驱动程序被删除(完整列表可用这里)，并在升级之前使用rmmod卸载模块。
