The destination partition has to be at least as large as the
original for a copy that's not file/inode based.

Very, very carefully.

You can use dd for the actual copying of unmounted partitions.

cpio can be used for file-based copying from mounted filesystem to
mounted filesystem

I hear that 'dump' can also be used but I've avoided learning how to
use that since 1985, and I see no reason to stop avoiding.
