The 'roll back' procedures on this page describe how to restore your previous version of SBC Edge (SBC) in the unlikely event that you encounter an issue with your SBC Edge upgrade.
Before you begin
Prior to rolling back your SBC Edge upgrade, ensure that you have a backup of your SBC Edge data for the version you intend to roll back to.
Warning: Restoring From A 3.1 or Higher Configuration Backup
Do not attempt to restore your version 3.0 or earlier SBC Edge configuration from a backup made using version 3.1 or higher release. Doing so will result in a complete user lockout and the system must be reset to factory default to recover.
Downgrading a node that has a value license or a Revised ASM (type Pentium or type Xeon) from release SBC Edge 6.1 to an earlier version is not allowed.
Performing the Rollback
Refer to the appropriate upgrade instructions below for your SBC Edge hardware configuration:
Rollback SBC Edge with a Built-in ASM
The instructions in this section may be best coordinated with your Sonus service representative.
Similarly to upgrading, to ensure the Sonus can communicate with the ASM, you must downgrade the SBC Edge Communication Service before downgrading the SBC Edge software.
- Remotely login to the ASM via Remote Desktop.
- Manually uninstall the current SBC Edge Communication Service from the Programs and Features via the Control Panel.
- From the Sonus SBC Edge Download Center, download the
SBC Edge Communication Service
.zipfile for the version that you are downgrading to.
- Open the
.zipfile and unpack it to a temporary folder. This will produce a
- Copy the
Setup.msionto a local folder directly onto the ASM.
- Launch the installer and proceed with the installation wizard.
- To ensure the SBC Edge Communication Service was properly updated, verify the Sonus SBC 1000/2000 Communication Service Version has changed to the intended version.
Important ASM Note
If you are downgrading from 2.0.x (or later) to → 1.3.x (or earlier), all disabled Network Adapters on the ASM must be enabled. This is because the 2.0.x (or later) upgrade disables one of the network adapters (by design), and it must be re-enabled if you're downgrading to 1.3.x (or earlier).
- From the Start menu - type View network connections and select it
You will find at least one disabled network adapter. Enable it as shown below:
Once the network adapter is enabled, you must set the necessary permissions to allow the downgraded SBC Edge Communication Service to Install ASM packages via the Sonus SBC Edge WebUI.
- From the Start menu - type Command Prompt and select it
Enter (or paste in) the following commands - the order is important:
The results will be similar to:
You now may proceed with rolling back the SBC Edge software version, follow the instructions below
Rollback SBC Edge Software
The Sonus SBC 1000/2000 keeps its system software (firmware) in containers known as "Application Partitions". There are two application partitions, one of which is Active. When the Sonus SBC 1000/2000 system is operational, it is running off of the Active Partition, and the remaining (inactive) partition serves as a spare.
You can rollback to the previous SBC Edge version stored in the inactive partition:
- To rollback the SBC Edge software, simply activate the inactive partition.
- Verify that you are booting from the new partition either by checking the active partition, or by Viewing the Software Version and Hardware ID.
- Restore the backup configuration data associated with the SBC Edge version you have downgraded to.
This completes the rollback procedure.
