Yes, This is possible.

You can directly upgrade from 11.4 version to 12.3 version for security products.

However, it would be recommended to go to 12.1X44 and then proceed to 12.3 version.

Hi,

 

Yes you can definitely go from 11.4 directly to 12.3 as both are EEOL junos version, but recommend to go to 12.1X44 and then move to 12.3 as there are few security checks implemented from 12.1X44 onwards to strengthen teh Junos code.

Hi,

 

Can you please also let me know the devise that you are trying to upgrade from 11.4 to 12.3.

update the output of the comand "show version"

Some devise cannot be upgraded to 12.3 Devise at all and hence  we need to know the chassis which you are trying to upgrade.

All low memory devises can not be upgraded to 12.3 code.

 

SRX100b/H, SRX110H, SRX210B/H/BE/HE, SRX220H, SRX240B/H/B2 do not support 12.3X48 image.

Last junos image supported on the above devises is 12.1X46-D65.
