Critical Warnings Before You Upgrade

  1. The 15.x Trap: Do not load JunOS 15.x on EX2200 unless you have a specific feature need. Many users report memory leaks, high CPU usage, and PFE crashes. Stick with 12.3R12-S15.
  2. Free Space is Mandatory: The EX2200 has limited flash (approx. 500MB). Run request system storage cleanup before adding new firmware.
  3. Don't Skip Versions: If you are on 10.x or 11.x, you cannot jump directly to 12.3R12. You will need to go to an interim 12.1 release first. Consult Juniper’s upgrade path document.
  4. No Downgrade Without Format: Once on 15.x, downgrading to 12.x often requires a full request system zeroize and fresh install—which erases your config.
