Hi Juniper team,
I tried to upgrade Junos from 15.1 to 17.4R2 in order to reach 19.3R2.
However, I failed to upgrade.
Can you tell me if any of my understandings below are wrong?
and
Could you please guide me on how to upgrade from 15.1 to 19.3R2?
#Basic information:
Model: SRX340
JunOS: 15.1X49-D150.2
#Original plan:
JunOS Upgrade path: 15.1X49 -> 17.4R2 -> 18.4R2 -> 19.3R2
# A procedure that I did.
Tried to upgrade via J-Web -> Administration -> Software -> Upload Package
1. Select "junos-srxsme-17.4R2.4.tgz"
2. Checked "Reboot If Required"
3. Checked "Do not save backup"
4. Unchecked "Format and re-partition the media before installation"
5. Click Upload and Install Package
6. After a while, I can see the normal success messages and shutdown message on CLI.
7. I was waiting for 30 minutes. However, I can not access the management port via J-Web and CLI both.
8. LED status:
- PWR: Solid green
- STAT: Solid red
- Management port: Solide green
- Other ports: Not operated
# A procedure for recovering.
1. I tried "Forced shutdown" twice.
2. SRX340 booted from the backup Junos image.
- WARNING: THIS DEVICE HAS BOOTED FROM THE BACKUP JUNOS IMAGE
3. I reviewed how to recover and tried below:
- request system snapshot slice alternate
- request system reboot
4. After rebooting:
- The system rebooted in normal via original JunOS(15.1X49-D150.2) successfully.
Thanks
JW
