I have really confused by junos upgrade and downgrade procedures.  I have an m7i that is running 10.4R9.2 and and am trying to get it to 10.4.9R8.5  I get the following error.



WARNING: The root filesystem is low on free disk space.
WARNING: This package requires 12451k free, but there
WARNING: is only -15416k available.

WARNING: This installation attempt will be aborted.
WARNING: If you wish to force the installation despite these warnings
WARNING: you may use the 'force' option on the command line.
ERROR: jinstall fails requirements check
ERROR: jinstall-10.4R8.5-domestic-signed fails post-install
Installation failed for package '/var/tmp/jinstall-10.4R8.5-domestic-signed.tgz'


I do see that I am out of space on the compact flash card so I tried booting from the hard drive and doing the software install.  Not sure where to go from here.  Any suggestions?

Try issuing this command "request system storage cleanup"  That should clean up your hard drive to give you enough space to upgrade/downgrade.  Be warned however, that it will delete all logs, old software versions, saved file, etc etc.  it pretty much leaves you with the operating systems installed.  Save what you want to keep!


Also, read the release notes.  There may be some underlying OS changes that will not permit a downgrade.
