You can use dd, but as others have said, dd is nicknamed disk destroyer. If it was me, I’d probably just copy the files, which will be slower but easier to do.

phanto’s suggestion of using gparted/kparted is also a good one. Another thing to keep in mind is that many cloning programs will clone the partition size as well, so you may need to use kparted when you’re done to grow the partition to the larger microsd size.
