@BubbaFromGA Thank you for your inquiry. We ask members to use their best professional judgement when determining if an activity meets the guidelines to submit. I would say that as long as the course redesign/update was significant and the majority of the information is new information, you may submit the CPEs. I would suggest keeping record of the changes in case the CPE submission is selected for a random audit.
If I can be of further assistance, please don't hesitate to reach out to me.
