Due to the hardlinks, the only way to copy the backuppc data pool from one
set of disks to another at anything like the expected speeds, is to use 'dd'
and copy the whole filesystem. 

So unmount your old and new filesystems, then dd your old partition to your
new partition, then grow your filesystem to fit the new partition.

As Les said tho, it's usually easiest to just leave the old data in place
tho, and build a new set of backups on the new disks.
