We introduce a new class of change operators. They are a generalization of usual iterated belief revision operators. The idea is to relax the success property, so the new information is not necessarily believed after the improvement. But its plausibility has increased in the epistemic state. So, iterating the process sufficiently many times, the new information will be finally believed. We give syntactical and semantical characterizations of these operators.
