Upgrading JunOS Software

Assumption: JunOS is downloaded and stored in an FTP server.

Step1: Download the necessary image from the FTP server. Save it in the /var/tmp folder.

user1@SRX-Router1> file copy ftp://user1@172.25.11.254/junos-vsrx-x86-64-19.2R1.8.tgz /var/tmp/   
Password for user1@172.25.11.254:
/var/home/user1/...transferring.file.........ush100% of 1127 MB 5426 kBps 00m00s

Step2: Verify the software package

user1@SRX-Router1> file list /var/tmp | match junos 

junos-vsrx-x86-64-19.2R1.8.tgz

user1@SRX-Router1> file list detail /var/tmp | match junos 

-rw-r--r--  1 user1   wheel  1182081022 Jun 2  12:57 junos-vsrx-x86-64-19.2R1.8.tgz

Step3: Upgrade the device (sample output below)

user1@SRX-Router1> request system software add /var/tmp/junos-vsrx-x86-64-19.2R1.8.tgz reboot
