how we can avoid overriding of quota when launched after changes?

Hi Chirag, If I am reading this correctly, this is a scenario where you have a quota in a survey and make changes to the quota in a Live Edit. When the survey changes are merged to the live study the Response Summary tool will notice the difference and provide a prompt to update the quota counts. If you choose to update them, in buckets where the definition has changed the system will work to move participants into whichever bucket(s) they now qualify for, assuming the quota limit has not been reached for them. For buckets that are new to the survey, the system will work to backfill the existing participant records into the new buckets they would have qualified for, again assuming that the quota limit has not been reached for them. But if you choose not to update the quotas then nothing will change for the existing participant records. Please reply to this comment if my initial understanding is not correct.
