Defaulting New Benefit Plans through Open Enrollment

Hello,

I read the "Request for Defaulting New Benefit Plans through Open Enrollment (Doc ID 642375.1)". It states that we can't configure to map terminating plans to other plans for default enrollment.

For our open enrollment, we need to map over 1000 employees from their current basic life benefit plans to the new ones.

I am hoping someone might have a solution to handle the mapping and willing to share.

Thank you in advance!
