Replacing a UDF Group With Family Table Instances
When a UDF group is replaced by a Family Table instance, the children of the old group are automatically mapped to the replacement Family Table instance. Editing the references of the children is only necessary if the number of references in the original group is different than that in the replacement group. To enable this automatic reference editing, set the group_repl_with_recycle configuration option to yes.
