You're right that actual class membership is not stored at CHQ. So the class membership follows the standard rules for each class, based on age and sex. That will take into account members who move in and out of the ward, and members who move to a new class at the beginning of a year or on a birthday, based on age. In general that will work just fine, except for issues such as split classes within age groups, combined classes across age groups, and individuals who have specifically been moved out of a class because of a specific need that doesn't match the default class rules.
If you want rolls that allow for all those exceptions you'll have to continue to use MLS until all that information is transmitted to CHQ. My guess is that you'll be waiting a while for that to happen.
Questions that can benefit the larger community should be asked in a public forum, not a private message.
