There is another 210 that is an HE version (opposed to this one's H version) that is running 11.2R4.3. I was scared I was going to brick this one since they are a little different.
Mine:
Model: srx210h-poe
JUNOS Software Release [10.4R3.4]
Another one I have access to:
Model: srx210he-poe
JUNOS Software Release [11.2R4.3]
If I could repackage the image somehow, I'd have felt ok about it, but a backup/restore concerned me since something could be different based on hardware or partitions. Would a backup/restore work between these 2? Then I could maybe upgrade to 12.1 from the 11.2?
thanks
