I am planning to upgrade SRX110HE and SRX210H remotely in our enterprise. It will be upgradation from JUNOS frm 12.1X44-D20.3 to 12.1X46-D65 on Branch SRXs. Need help with below queries:
I am worried because It will be nearly impossible to go to datacenter if things go wrong?
Thanks a lot Suraj for your quick reply. It will really help me to proceed further and clearing my doubts.
If "reqest system software add \var\tmpfilename.tgz no-copy reboot" fails then how device will come up?ANS: If upgrade fail device wont reboot. If there are any issues during reboot, device will try booting from backup partition which is 12.1X44
Does it mean that if upgrade fails then it wont reboot and keep on running from snapshot stored in primary partion?
Do you have any suggestion to prepare for worst case scenario if everything goes wrong?
Sorry to bother you mate.
