This is discussed by about every new user on the mail list, but the 
short answer is that there is not a good way to do it.  Rsync will work 
but will take a very long time.   Another approach is to image-copy the 
partition, then expand the filesystem on the new disk.  That would be 
faster but takes some obscure commands.  Or there is this approach: 
http://sourceforge.net/apps/mediawiki/backuppc/index.php?title=Move_backup_data 
which is somewhere in between.

My recommendation is to build a new box and keep the old one around for 
emergencies until the new one accumulates as much history as you need.
