Upgrading Ops Center Administrator by using backup and restore

You must use the backup and restore method for upgrading in the following cases:

You are moving your Ops Center Administrator instance. In this case, you must upgrade by backing up your existing Ops Center Administrator instance, installing a newer version, and then restoring the previous instance. When upgrading, you can upgrade from 10.0.x or later to the current version.
You are migrating to a different container runtime (for example; migrating from Docker to Podman). In this case, you must upgrade by creating a backup of your existing Ops Center Administrator instance before removing the older container runtime and installing a new one.
When Ops Center Administrator is working in host mode, the user-defined port numbers for accessing the Ops Center Administrator are migrated but the internal service port numbers are not migrated to a new instance when you restore. In this case, ensure that the Ops Center Administrator default port numbers are not in use, and change the port number manually again after the installation. For details about required port numbers, see Port requirements. To configure a port number in a new instance, see Modifying the internal port allocated by Ops Center Administrator for host mode.

Choose one of the following installation methods:
- Use the preconfigured media ISO to deploy an OVA. The OVA installation deploys a VM with an operating system, Podman, and Ops Center Administrator. If the current version was deployed by using the stand-alone preconfigured media, you can use the consolidated Ops Center preconfigured media to deploy a new version.
- Use the application installer to enable maximum control of the environment. The installer must be deployed in a Podman-compatible environment that contains only the Ops Center Administrator application.
  Note: If you use the json-file logging driver, set the maximum log size to 50 MiB and the maximum number of files to 5.
From the currently installed version, open a browser, and enter the following URL in the address bar:
```
https://ip-address:port/vam
```
where:
- ip-address is the IP address of the Ops Center Administrator server.
- port is the port number of the Ops Center Administrator. The default port number is 443 or 20961.
- When upgrading from Ops Center Administrator installed using the Ops Center preconfigured media or application installer:
  - User name: sysadmin
  - Password: Specify the current password. The default password is sysadmin.
- When upgrading from Ops Center Administrator installed using the stand-alone preconfigured media:
  - User name: service
  - Password: Specify the current password. The default password is Chang3Me!.
When the virtual appliance manager opens in the browser, click the Backup icon () to download a backup file of the currently installed version. The file may take a few minutes to start downloading.

Note: Ensure the virtual appliance manager log level is set to INFO before you upgrade. If it is set it to DEBUG or TRACE, the upgrade may fail with errors.
After downloading the backup file, shut down the currently installed version.
- If you used the Ops Center Administrator installer method, delete the Ops Center Administrator containers and images on the system before running the new installer. For more information, see Removing Ops Center Administrator.
- If you used the Appliance model, the VM containing Ops Center Administrator is shut down at this time. You may want to determine a maintenance window to do this because Ops Center Administrator is unavailable until the upgrade is complete.
- If the current version was deployed by using the application installer and if you want to migrate to a different container runtime (for example, migrating Docker to Podman), remove the old container runtime and then install the new container runtime on the host OS.
Deploy the next version using the method of your choice (preconfigured media or installer).
In the new instance of Ops Center Administrator, open a browser, and enter the following URL in the address bar:
```
https://ip-address:port/vam
```
where:
- ip-address is the IP address of the Ops Center Administrator server.
- port is the port number of the Ops Center Administrator. The default port number is 443 or 20961.
The default login credentials are sysadmin/sysadmin
When the virtual appliance manager opens in the browser, click the Restore icon (). You are prompted to upload the backup file that was downloaded earlier. Choose the file and upload it to the new Ops Center Administrator instance.
The Ops Center Administrator appliance restarts. It may take up to an hour to restore the configuration. After the appliance is running, the upgrade is complete. (Optional) If the upgrade completed successfully, you can delete the VM containing the previous version of Ops Center Administrator.
