You might find it easier to do a reinstall and then copy any data over -
it will be at least as quick as shrinking the first data disk and using
dd to copy the data from one SD card to the other.
If you have any particular software that you must have - get a listing of
what's on the first card and copy that list over as the list of packages you
install
dpkg --get-selections > myfile
dpkg --set-selections < myfile
will probably do it followed by an apt update.
Then it's just a question fo copying over personal files and config files
from the old SD card.
All the very best, as ever,
