So if I understand correctly, using the old switch, everything is good???

If that's the case, put the old switch back in place and login to all your machines and do the ping test.  It should be good.  Now, don't logout, just change the switch and look at the connection status for all your machines.  Are they still good?  Can you do the ping test now and is it good?
