A quick kernel swap?

[Sean Hafeez]

All things being equal, same hardware, same version of the same build 
of 4.8, etc... I have one box with a kernel w/out DUMMYNET and one with 
a kernel w/DUMMYNET. If I were to copy the DUMMYNET kernel to the 
non-DUMMYNET would it work? The other issue I have is space. The system 
is running off flash. Can I delete the running Kernel before I copy up 
the new one?

Thanks!
