You could use copy but tar tends to be a better alternative. Just tar up your 
rootfs and then extract to your new card. Under most *nix variants you need to 
extract using the 'p' parameter to preserve file permissions. Also make sure 
you are not mounted with the option 'nodev'.

With a new u-boot it's also possible to consolidate the kernel and rootfs into 
one partition to ease kernel upgrades.
