The procedure to revert the 

Spacevars
0series4
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.

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.
