I have a MAPS subscription that will expire on 1/22/2026. I have ALREADY purchased the new Partner Launch program and see that under my Products. HOW DO I migrate the email addresses from the OLD MAPs subscription to the NEW Business Launch subscriptions

I have a MAPS subscription that will expire on 1/22/2026. I have ALREADY purchased the new Partner Launch program (billed and invoiced) and can see that subscription) under my Products.

My Questions:

1. How do I migrate the email addresses from the OLD MAPs subscription to the NEW Business Launch subscriptions withOUT any DISTRUPTION in my email or loss of data? What are the steps that I need to do?
2. How do I apply the keys? Are there keys like in the MAPs program?

I was told that I could have both in affect - until I test and MAPS expires - but is that true?

I need to do this right away - as my subscription is expiring and do not want users to lose any access to their email.

What is the best practice to do this migration between programs? Thank you! Terri D.
