Hi List,

We recently bought a Juniper M20 to expand our lab setup.
It runs JUNOS 5.5R2.3

I want it to upgrade it to JUNOS 9.0 however we started to archive JUNOS 
versions since 7.1R1.

However a request system software add validate reboot 
jinstall-7.1R1.3-export-signed.tgz gives the following error:

59627557 bytes transferred in 142.9 seconds (407.60 kBps)

Ofcourse the difference between 7.1R1.3 and 5.5R2.3 is way to big, any idea 
how to get hands on a 6.x jinstall package?

As the router is only for our juniper lab we dont have it under contract so 
opening a JTAC ticket is not an option.

Any ideas?

Thanks,

Leon
