While every customer's environment is impacted differently, several are known to exist in 4.2(4).

4.2(6) is the minimum preferred release in the 4.2 train though you may wish to consider a 5.x or 6.x release for additional features and patches.  Please consult the Release Notes for specific defect & feature information.

Ok,

What happen if i do nott upgrade Nx-os to 4.2(4)?

Can cisco give me technical support with this version? or is necessary to do minimum upgrade 4.2.(6)?
