Device upgradtion consideration

Device up-gradation consideration these are thinks better to consider while upgrading the device with the newer one .
 power [ AC/ DC  / socket type ( C14/C15 - C19/C20 etc) 
 Rack type and mounting brackets and screws
 IOS  Feature comparison  does all the features supported in the newer image - double check [ sometime we downgrade the device eg: move the powerful device where most needed]
 Access to the technicians 
 Interface Type and fibre patch cords [ lc / sc / fc ] , length. 
 If we are swapping the device from different location make sure the transport and proper wrapping / cartons. 
 Then actual migration plan :)
