# Sending a final reminder from old event platform

As a final step to migrate members who might still be active on your old platform, creating a new activity will get them to sign up on Commudle and join your community.

## Create your next event on old platform

* Create your next event on both old platform and Commudle.
* On the existing platform, add the link to registration as external link and use the link to your event from Commudle on the old platform.
* When someone registers for your event they will automatically become a member of your community.

This sums up the migration!
