Root Cause
First, N8300 doesn’t support upgrade online, so it needs to stop all business. Upgrade means reset system.
Second, we can’t lose the configuration of N8000, so we must save the configuration to storage. And when upgrade is finished, exporting it back.
Last, make sure the versions of N8000 and T series. At the end of 2011, the version of N8300 is v1r2c00spc003 and T series is v1r1c01scp013.
Contract R&D before operate.
