CentOS 7.9から8.5へのアップグレードは完了していません。修正のための提案はありますか？

Windows CIFファイルサーバーとNFS vmware共有で主にZFSを実行するCentOS 7.9サーバーがあります。 v7はうまく動作します。移行のために飛躍/上昇を試みましたが、NFSで失敗したため、Almaに移動できることを確認するためにv8にアップグレードしようとしました。

私は次のステップに従いました。https://techglimpse.com/how-to-upgrade-centos-7-to-centos-8-linux/このコマンドは失敗します。

dnf -y --releasever=8 --allowerasing --setopt=deltarpm=false distro-sync

依存関係エラーがたくさんあります。

しかし、

• cat /etc/redhat-release見せてくださいCentOS Linux release 8.5.2111。
• カーネルはまだ3.10.0-1160.90.1.el7.x86_64

実行するdnf updateと、98個のパッケージをインストールし、746個のパッケージを更新し、255個のパッケージをスキップします。しかし、失敗します。
