Resizing and moving a Debian instance from a 500 GB drive to a 250 GB 
drive requires a lot of expertise.


I would take the KISS approach -- backup the system configuration files 
and data, remove the 500 GB drive, install the 250 GB drive, do a fresh 
install onto the 250 GB drive, and reconfigure/ restore.
