All current STRM platforms are shipped with an old software image (i.e., 2009.2). In situations where an STRM appliance which was running a more recent version (i.e., any version later than 2009.2) is replaced, the new STRM is shipped with old software image. This article explains how to do a clean installation to get back to the desired (more recent) version.

This procedure avoids stepped upgrades to the desired version, in cases where there is no data to be preserved.

Perform the following steps:

1. Add the desired software version image in the Recovery partition  (see Knowledge Base article KB17542 [juniper.net] ).

• Reboot the system.

• The system restarts and enters the re-install menu.

• Select the desired software image. When prompted to flatten the system,  type flatten and press Enter . The normal installation process continues from this point onwards.
