HI,

1. We have Two Nexus switches 5010 working as primary & secondary reaches to high/peak CPU utilization intermittently. This cause response problem in applications. current Version is 4.2(1)N1(1)

2.  Also Need to Upgrade the OS for these switches to latest OS 5.1(3)N2(1).

Need to know whether direct upgrade to version 5.1(3)N2(1) from 4.2(1)N1(1) is possible or i need to step through intermediate versions?

Also need upgrade procedure for nexus switches.
