The procedure to revert the 

Spacevars

application using the EMA is provided below. You can only revert the application for upgraded systems (offline or LSWU). You cannot revert a system to an older version after a server/system is ISO, or after installing the SBC software.

The SBC application revert from this release to the previous version is performed using the SBC EMA with the following prerequisites:

The firmware is not reverted back to an earlier version because it is backward compatible with earlier

0product
versions.


Any configurations performed after the upgrade will be lost after the Revert. Once the revert completes, the configuration rolls back to the time stamp in the 'Last Used' field.

Once a revert is performed to a valid pre-6.0 SBC release, an upgrade to another pre-6.0 release is not supported. Upgrading to any other pre-6.0 releases requires the ConnexIP re-ISO installation. Refer to Re-Installing ConnexIP Operating System for SBC 5000 Series or Re-Installing ConnexIP Operating System for SBC 7000 Series for more information on ConnexIP re-ISO installation.


  • Only the systems upgraded (offline or LSWU) can be reverted. The system can not be reverted to an older version when the server/system is ISOed or the SBC software is installed.

      The Revert Software application simultaneously reverts both the Active and Standby server. Continuing the revert will reboot the upgraded server(s) to an earlier release. During this process, the browser session is lost necessitating logging back into the session.


      The Revert Software starts and changes the boot version to earlier version in both the active and standby server. For example, in this case, it is 06.02.00R000 version. You can see the revert status in the Log section.
