SRX5800 Downgrade from 19.4R1 to 12.3X48-D100

  • 1.  SRX5800 Downgrade from 19.4R1 to 12.3X48-D100

    Hello,

    I'm looking for the procedure and Junos to downgrade an SRX5800 to 12.3X48-D100.  I can't seem to find anything.  Getting the following error:

    Error:/usr/libexec/ui/downgrade: the bootstrap installer is missing

    Here is what I've been able to find out on the downgrade, unfortunately I don't' see any interim code to download.  USB install is not an option, try the following path to downgrade and see if that works.

     

    19.2 -> 17.3 ->12.3

    Or

     

    19.2 -> 18.4 -> 15.1X49-D220.2 -> 12.3
