The rollback procedures on this page describe how to restore your previous version of SBC SWe Edge in the unlikely event that you encounter an issue with your upgrade.
Downgrade Release 9.0 to a Previous Release - Guidelines
For downgrading SBC SWe Edge 9.0 to a previous release: A downgrade protection recovery partition has been included in Release 9.0 to simplify the booting process. As a result, you must downgrade 9.0 to a minimum downgrade release listed below:
| Current Release | Minimum Downgrade Release Allowed |
|---|---|
| 9.0.0 and later | 8.0.5 or 8.1.6 |
| 8.0.5* and later | 8.0.5 |
| 8.1.6* and later | 8.1.6 or 8.0.5 |
*Not supported in AWS.
Before you begin
Prior to rolling back your upgrade, ensure that you have a backup of your data for the version you intend to rollback to.
Performing the Rollback
The SBC SWe Edge keeps its system software (firmware) in containers known as Application Partitions. There are two application partitions, one of which is Active. When the SBC SWe Edge 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 SWe Edge version stored in the inactive partition:
- To roll back SBC SWe Edge, 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 (SBC 1000/2000, SBC SWe Edge).
- Restore the backup configuration data associated with the version to which you have downgraded.
This completes the rollback procedure.
