recommend you perform the upgrade in two stages: first to an intermediate release and
then to the higher-numbered release you want to run. This restriction is not applicable
if you upgrade your software remotely through Telnet or FTP.
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, if you are
upgrading the software using a new NVS card, 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.

modules, see:
JunosE System Basics Configuration Guide, Chapter 6, Managing Modules
Upgrading NVS Cards on SRP Modules on page 79
This section describes how to install higher-capacity NVS cards on SRP modules. The
procedure you use depends on the number of SRP modules in the system. A new NVS
card already contains the software release you ordered.
NOTE: The new NVS card must contain the same software release that you
are running on the system.
If the system contains only one SRP module, you must power down the system before
you upgrade the NVS card.
CAUTION: If you do not use the halt command before removing or powering
down an SRP module, the system's NVS card can become corrupted.
To upgrade the NVS card on a system that contains one SRP module:
