That would seem to depend on what get_next_project_number() does, the
contents of which are unknown.
get_next_project_number() gets the next project-number based on some custom logic.
What would be the best way to update all project's project-number having the oldes project get the first number returned by get_next_project_number() etc.?
Thanks.
