Time Machine backups after changing Logic Board

Important details about Time Machine backups.
Main article covers altering the .SparseBundle file (several hundred gigs) that relates to the old machine, so that it now recognises the new mac Logic Board's MAC address and HDD UUID.  

Forum posts stress the importance of a SuperDuper clone, that is way more efficient in restoring a machine to scratch.  
There are also others who state that Time Machine restorations can be done via the Leopard install disc and selecting Utilities > Restore From Time Machine.
