After deploying the meteor application - say, foo.meteor.com - can you rename the application URL?
It doesn't look like this , but you can always just delete it and deploy a new one:
meteor deploy --delete YOUR_APP meteor deploy YOUR_NEW_APP
The Meteor command line has no command to rename a deployed application.
But you can just deploy your application with a new name instead of the old one:
meteor deploy new_app_name.meteor.com
