Hi,
I have been asked to upgrade a good bunch of live srx210H2s to the recommnded junos version but I have never done this before and don't have a test SRX to test it on.
Upgrade will be from 12.1X44-D15.5 to 12.3X48-D65.
I got to the point of getting an image to the SRX /var/tmp folder, did a checksum confirmation and I am ready for "request system software add /var/tmp/junos-srxsme-12.3X48-D65.1-domestic.tgz no-validate reboot" ... but now I am a bit concerned if the config will compatible or do I have to upgrade to the intermidate verions.
will "request system software add /var/tmp/junos-srxsme-12.3X48-D65.1-domestic.tgz validate" just check if the config will have no issues and it is safe to procced or will it install the new firmware and give a message with any issues?
Please advise.
Thanks you
