DO NOT REPEAT NOT DELETE THE PARTITION
If you do, you will lose everything that was on it: your books, the Kobo software, everything.
After writing the image to the new card, use a partition manager to extend the partition so that it incorporates the free space. This will update the tables on the card and in the partition so that they recognise the new size. To check, you can run a file system check on it to ensure that everything's OK.
