# 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! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
