Updating the Operating System of the Catalogic vStor 4.8.0

Before upgrading the Catalogic vStor product components in the appliance, take the following steps to update the operating system from CentOS Linux 7 to AlmaLinux OS:

Open the hypervisor: either VMware vSphere Client or Microsoft Hyper-V Manager. Select the VM for the Catalogic vStor 4.8.0 appliance. Open the virtual monitor for this VM.
In the virtual monitor, log in to the shell session of the Catalogic vStor appliance as admin.
Tip. Do not use an SSH client.
Restart the system, and keep watching the virtual monitor window.
```
$ sudo reboot now
```
On the virtual monitor window, the system prompts you to select the kernel; select CentOS Linux (3...) 7 (Core). After the system starts, ensure that the kernel version in the login page shows the 3 series. If you are seeing the 4 series, repeat this step.
Log in to the shell session as admin and switch to root access:
```
$ sudo bash
```
Go to the directory in which the upgrade files are stored:
```
# cd /home/admin/update/
```
Run the upgrade script with the --upgrade-os flag:
```
# update_vstor_4.8.1.sh --upgrade-os vstor_with_os_full_4.8.1_physical.iso
```
Follow the instructions on the screen. The script initiates the pre-upgrade test. When the test fails, see the logs as instructed on the screen, and ensure that you have completed all the prerequisites. Or, contact Catalogic Technical Support for assistance.
Wait until the upgrade script is completed and the system automatically restarts.
After the first system restart, open the virtual monitor on your hypervisor and ensure that the system is installing the Leapp installer with the updater kernel. Then, the system restarts automatically again.
After the second system restart, run the following command and ensure that the operating system is now using AlmaLinux OS 8:
```
$ cat /etc/centos-release
```

Now, you are ready to update the product components of Catalogic vStor.
