Even if you swap one drive at a time and get the virtual disk size increased, the OS partition would also need to be resized. Its time consuming and will greatly affect server performance. Safest way is to install the server backup feature, do a system state backup, pull the old drives out (with existing data intact that you can always roll back to) create the new array and restore.
