Not sure what you're asking.
It already has a rule "minimumTotalAssignments" and a rule 
"maximumTotalAssignments":

Adjust those as needed.

and mark the old data as immovable (easiest way is in the example 
implementation indeed to advance the planning window beyond the old data)

Expand the domain model of the example implementation to represent this 
complexity.
Then adjust the score rules so they only apply to the active contract of 
an employee.
It gets interesting when an employee switches contract in the middle of 
a planning window...
