 If you run the Leapp upgrade from RHEL 8.10 to 9.4 or 9.5, the upgrade process might not continue after the required reboot. Instead, the VM boots back into RHEL 8.10 without loading the special upgrade initramfs.

 > [!IMPORTANT]
 > If the Leapp upgrade still fails without an obvious reason (such as when upgrading from version 7.9 to version 8.10 or from version 8.10 to version 9.5), don't upgrade to the latest version. Instead, try to upgrade to an intermediate version (such as from version 7.9 to version 8.8 or version 8.10 to version 9.4) by specifying the `--target x.y` flag. After the intermediate upgrade is successful, you can try to upgrade to the latest release.
