[j-nsp] Downgrading Junos on M10i

[Samuel GAY]

David,

1) Download these versions of JUNOS (you need to have a account on 
Juniper website) :
https://download.juniper.net/software/junos/8.3R3.4/jinstall-8.3R3.4-domestic-signed.tgz
https://download.juniper.net/software/junos/8.2R4.5/jinstall-8.2R4.5-domestic-signed.tgz

2) Transfer them to the router and install 8.3 version
 > request system snapshot (to have on the hard disk a copy of your system)
 > request system software add jinstall-8.3R3.4-domestic-signed.tgz reboot

3) Install the 8.2 version :
 > request system software add jinstall-8.2R4.5-domestic-signed.tgz reboot

4) If all is correct you can do a backup of your new system on the hard 
disk :
 > request system snapshot

Hope this help you,
Samuel
