当前RHEL最新版本是8.4，如何将azure机器从RHEL7.9只升级到8.2呢？

和Azure support讨论后发现目前没有啥特别的办法一步到位，只能先将OS升级到最新版本再降级

1) Upgrade the Azure redhat OS from 7.9 to 8.4

tranfer leapp-data14.tar.gz to Cloud VM.

scp yourid@10.117.xx.xx:~/leapp-data14.tar.gz .

#here is just an example to tranfer files.

yum install leapp leapprepository

yum install leapp-rhui-azure tar -xzf leapp-data14.tar.gz -C /etc/leapp/files

yum update reboot the VM leapp answer --section remove_pam_pkcs11_module_check.confirm=True --add

rmmod pata_acpi

rmmod floppy

leapp preupgrade --no-rhsm

leapp upgrade --no-rhsm

uname -a && cat /etc/redhat-release

2) Downgrade the OS from 8.4 to 8.2

rpm -qa |grep redhat-release

cat /etc/os-release

yum install redhat-release-8.2 -y

rpm -qa |grep redhat-release

cat /etc/os-release"

1.3 "Patch the OS

1.3.1 lock the minor version to 8.2 and switch VM to using EUS repository

yum --disablerepo='*' remove 'rhui-azure-rhel8'

wget https://rhelimage.blob.core.windows.net/repositories/rhui-microsoft-azure-rhel8-eus.config

yum --config=rhui-microsoft-azure-rhel8-eus.config install rhui-azure-rhel8
