JUNOSe 10.2.2 Release Notes

Release Installation
Upgrading from Release 5.1.1 or Lower-Numbered Releases to
Release 6.x.x or Higher-Numbered Releases
Release 5.1.1 or lower-numbered releases support application images only up to
172 MB. To install larger application images for Release 6.0.0 and higher-numbered
releases, you must first install Release 5.1.2 (or a higher-numbered 5.x.x release).
This enables the system to support application images greater than 172 MB. For
example, you cannot go from Release 5.1.1 to Release 7.2.0 without first upgrading
to Release 5.1.2. See the following table for compatibility of releases.
Your software upgrades may be available remotely through Telnet or FTP, or may be
delivered on a new NVS card. Depending on how you access the software updates,
there are two different procedures to follow. For more detailed information on
installing software, and about NVS cards and SRP modules, see the following
documents:

Moving Line Modules Between Releases
The Juniper Networks ERX1440 Broadband Services Router employs a 40-Gbps SRP
module and a new midplane. Release 3.3.2 was the first software release to support
the 40-Gbps SRP module and midplane. Before you can transfer a compatible line
module from a Juniper Networks ERX705, ERX710, or ERX1410 Broadband
Services Router to an ERX1440 router, you must first load Release 3.3.2 or a higher
release onto the current router, and then reboot the router to load the release onto
the line modules. If you then move any of those line modules to an ERX1440 router,
that router is able to recognize the line module.
If you move a compatible line module from an ERX1440 router to an ERX705,
ERX710, or ERX1410 router, the module loads properly in the new router regardless
of the release.
