[c-nsp] CRS1 downgrade from 4.0.1 to 3.6.2

[Vikas Sharma]

Hi,

I have upgraded CRS1 to 4.0.1 from 3.6.2. Upgrade worked fine and it is
running 4.0.1. But the issue is I am not able to downgrade it back to 3.6.2

If I am trying to run any install command I see similar output -

RP/0/RP0/CPU0:crs1.BLB(admin)#install commit

Install operation 402 '(admin) install commit' started by user 'colt123' via

I have also checked on the active and inactive files and could not locate
upgrade package on active disk (boot disk). Does anyone has faced similar
issue?
