Hey Mike,
I like to read posts about successful migrations
Makes me very happy that the component is helping people save time.
Yes, after a successful installation you can remove the component. Keep in mind -> if you've migrated the users -> you'll need to keep the "authentication - Cmigrator" plugin -> this one is responsible for the authorization of users when they try to login on the site. Without it they won't be able to login.
Regards,
Daniel
