The 'roll back' procedures on this page describe how to restore your previous version of 

Performing the Rollback

 with a Built-in ASM

The instructions in this section may be best coordinated with Ribbon.

Similarly to upgrading, to ensure the

1. Remotely login to the ASM via Remote Desktop.
2. Manually uninstall the current

   Communication Service from the Programs and Features via the Control Panel.
3. From the Ribbon Support Portal - Download Center, download the 
   Unable to show "metadata-from": No such page "_space_variables"
   Communication Service .zip file for the version that you are downgrading to.
4. Open the .zip file and unpack it to a temporary folder. This will produce a Setup.msi file.
5. Copy the Setup.msi onto a local folder directly onto the ASM.
6. Launch the installer and proceed with the installation wizard.

7. To ensure the 

   Unable to show "metadata-from": No such page "_space_variables"
   Communication Service was properly updated, verify the SBC 1000/2000 Communication Service Version has changed to the intended version.

   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).

      nfsadmin server creategroup Sonus SBC 1000/2000
      nfsadmin server addmembers Sonus SBC 1000/2000 169.254.1.1
      nfsshare public -o rw=Sonus SBC 1000/2000 root=Sonus SBC 1000/2000
      

   3. The results will be similar to:

      
      

      C:\Users\Administrator>nfsadmin server deletegroup Sonus SBC 1000/2000
      The settings were successfully updated.

      The settings were successfully updated.
      
      C:\Users\Administrator>nfsadmin server addmembers Sonus SBC 1000/2000 169.254.1.1

 Software

The Ribbon 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 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 

1. To rollback the

    software, simply activate the inactive partition.
2. 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).
3. Restore the backup configuration data associated with the 
   Unable to show "metadata-from": No such page "_space_variables"
   version you have downgraded to.

This completes the rollback procedure.
