This script performs a one-time operation to create the new combined password strength
setting for virtual accounts (Email, FTP, Web Disk) based on the highest value from the
existing settings, and deletes the old ones. It is run automatically on initial upgrade
to 11.54. You may also run the script manually, but it will only perform the operation if
it has not already been done.
