JUNOS Upgrade

I have a copuple of SRX100H2 and I need to upgrade the operating system, so lets move on.

You need a service contract with Juniper Networks in order to download the latest version of the Junos Operating System, at the time of this writing the version is: 12.1X44-D45.2

I have placed the Junos image in my ftp server (3CDaemon)

The first step prior to the operating system upgrade is ... copy the new Junos Operating system to the device. Juniper recomends to copy the operating system to the /var/tmp/.

root>file copy ftp://intruder@192.168.1.2/junos-srxsme-12.1X44-D45.2-domestic.tgz /var/tmp
Password for intruder@192.168.1.2:

and after a while

/var/tmp//...transferring.file.........YN9rVW/100% of  131 MB 1124 kBps 00m00s

root> file list /var/tmp/

/var/tmp/:
cleanup-pkgs.log
eedebug_bin_file
gksdchk.log
gres-tp/
idp_license_info
install/
junos-srxsme-12.1X44-D45.2-domestic.tgz
kmdchk.log
krt_gencfg_filter.txt
pics/
policy_status
rtsdb/
sec-download/
spu_kmd_init
vi.recover/
vpn_tunnel_orig.id 

And once the new operating system is copied on the device, we can proceed to upgrade the operating system.
