Can Precision Bridge restrict the data that is migrated?

Yes, within Precision Bridge you can use Source Filtering to construct a query that defines the records that you want to migrate on a table-by-table basis.

You can also restrict the migration of records to related migrations, for example, only migrate the tasks that belong to tickets that have themselves been migrated.

More complex restrictions that cannot be implemented by either of the above may be facilitated by making use of the PERFORM_COND_ACTION Assignment Function which can skip or error records based on a calculated condition.
