Juniper Junos – How to Upgrade from 11.4R5.7 to 12.4R6.6

juniper-junosswitch

I've been trying to upgrade the Junos version on some switches and most have gone fine using;

root@host> request system software add /var/tmp/jinstall-ex-3200-12.3R6.6-domestic-signed.tgz

However some of them show this instead of the normal "reboot immediately.."

Done with validate on all virtual chassis members

Before returning to prompt.

I've tried rebooting the switches and looking through messages log, however I'm not sure what I'm looking for.

Has anyone else experienced this or knows of a fix?

Model: EX4200-24T

The message itself, just means that it validated the software for all members of the VC. How many members does 'Show virtual-ch' display? Remember, members running different versions, cannot form a virtual chassis.

Can you try the same install using the 'no-validate' suffix?

Btw, it is possible to do NSSU on EX-series. Again, capabilities and version must match.
