No, because you can't assume that all existing preferences will be  
saved again during this period. It even is very unlikely because most  
preferences are set once in the beginning, and never again.

Not in a single mail. Composite is development pattern that is used to  
deal with two objects of similar classes at the same time.

For your case you rather want to write a script that reads all users'  
preferences from a Prefs_sql instance and write them to a Prefs_ldap  
instance.
