Notes:
-
KB30446 - SRX Junos SRX5K Hardware / Software compatibility matrix.
-
TSB17655 - On the SRX5000 series with SRX5k RE-13-20 a software upgrade to Junos release 12.3X48-D80, D85, or D90 may fail the pre-check due to insufficient space available on the compact flash.
-
For Junos OS upgrade paths instructions for SRX platforms, please see KB36620 .
-
Notes for upgrading from Junos 15.1X49 releases to 19.4R3 or 19.4R3 based Service Releases:
-
Junos OS upgrade from 15.1X49 directly to 19.4R3 or 19.4R3 based Service Releases is supported for all SRX platforms (ISSU is not supported). Note: PR1572963 - Junos OS upgrade from 15.1X49 directly to 19.4R3-S2 fails on SRX5400 / SRX5600 / SRX5800.
-
In case you would need to roll back or downgrade from 19.4 to the 15.1X49 release on SRX1500, SRX4100/4200, SRX5k, or vSRX, all files on the device may be lost. Hence it is important to back up the relevant files (configuration, license-keys, etc) before the upgrade and have console access during the upgrade and during a potential rollback if required.
-
For vSRX the following limitations apply when upgrading from 15.1X49 directly to 19.4R3 or 19.4R3 based Service Releases:
-
The file system mounted on /var usage must be below 14% of capacity.
Check this with
root@vsrx> show system storage | match " /var$"
/dev/vtbd1s1f 2.7G 82M 2.4G 3% /var
Note: The CLI command ‘request system storage cleanup’ may help reach that percentage if needed -
The Junos upgrade image must be placed in the directory /var/host-mnt/var/tmp/
request system software add /var/host-mnt/var/tmp/ -
It is recommended to deploy a new vSRX VM instead of performing a Junos upgrade. That also gives the option to move from vSRX to the newer and more recommended vSRX 3.0.
-
-
ISSU is not supported when upgrading from Junos 15.1X49 to any higher versions.
-
KB34945 - When Junos Space Security Director is used for managing the SRX configuration and the AppFW, IDP, or UTM features are used, then when upgrading to Junos 18.2R1 or higher, the SRX configuration needs to be migrated to the new Unified Policies style and Security Director version 19.3 or higher is required.
-
Starting with Junos OS Release 17.3, when you upgrade from Junos OS Release 15.1X49 to Junos OS Release 17.3 or higher, or downgrade from Junos OS Release 17.3 or higher to Junos OS Release 15.1X49, you must update the IPS signature package by downloading and installing the IPS signature package update.
