This will be the first time I am upgrading a Juniper device.
I am planning on upgrading a SRX 220 next week. I went through the Juniper guides and feel comfortable about the upgrade. Just in case if anything goes wrong, is there anyway I can revert back to the previous version? I believe I can make a snapshot of the OS/Configs by issuing 'request system snapshot'. Am I right?
And how do I install the 'Snapshot' back in the device?
Please advise any precaution I should take before the upgrade?
