Upgrading or downgrading the software
You can upgrade, downgrade, or revert to a backup version of the SteelFusion Edge software in the Administration > Maintenance: Software Upgrade page.
The top of the page displays the current version number and the backup version.
The SteelFusion version history appears at the bottom of the page. Select a column heading to sort the column in ascending or descending order.
The RiOS software upgrade is separate from the hypervisor upgrade. Upgrading or changing the RiOS version does not affect the ESXi version. For details on upgrading the hypervisor, see
Upgrading the hypervisor.
To upgrade your software
1. Download the software image from the Riverbed Support site to a location such as your desktop. Optionally, you can download a delta image directly from the Riverbed Support site to the SteelFusion Edge. The download image includes only the incremental changes. The smaller file size means a faster download and less load on the network. To download a delta image, skip to Step 2.
2. Log in to the Management Console using the Administrator account (admin).
3. Go to the Administration > Maintenance: Software Upgrade page and select the Add Image tab.
4. Select one of these options:
– From URL - Type the URL that points to the software image in the text box. You can use HTTP, HTTPS, FTP, or SCP formats for the URL.
– From Riverbed Support Site - Click this option and select the target release number from the drop-down list.
– From Local File - Browse your file system and select the software image.
5. Specify a name for the image.
If you specify a name that already exists on the appliance, the new image overwrites the existing image.
6. Click Add Image.
When the image transfers to the appliance, the Install Image section is available.
7. Click Install.
The system installs the image in the backup partition and sets the option to load the backup partition version on reboot.
8. Reboot the Edge.
If you upgrade to a new software release, change the password, and then downgrade to the previous release an invalid password message appears.
Downgrading the software
If you want to downgrade to a previous version of the Edge software, you must downgrade to a version of the software that has previously run on your machine.
When you downgrade the software, Edge reverts the ESXi version to the version supported in the installation image. If you upgraded the ESXi using vCenter, the system cannot restore the state and ESXi starts with the initial configuration.
Edge appliances cannot use an encrypted RiOS data store with an earlier RiOS version, unless the release is an update (9.0.x). For example, an encrypted RiOS data store created in 9.0.1 would work with 9.0.3, but not with 9.1.
Before downgrading to an earlier software version, you must select None as the encryption type, clear the RiOS data store, and restart the service in the Optimization > Data Replication: Data Store page. After you clear the RiOS data store, the data is removed from persistent storage and cannot be recovered. If you are using the server-based backups feature, you must delete all backup policies and clear snapshots on the storage array before downgrading. For details, see the SteelFusion Core User Guide.
To switch to the backup version
1. Log in to the Management Console using the Administrator account (admin).
2. Go to the Administration > Maintenance: Software Upgrade page and click Switch to Backup Version.
3. Reboot the appliance or click Cancel Version Switch to cancel.
