Migrated ELB to ALB, my EBS profile didn't update

I have an elasticbeans environment that had been using an "classic" load balancer. I ran the widget to update that to an Application load balancer. But EBS is still pointing at the classic instance, which is gone. Its not obvious how to fix this without rebuilding. I can change the config of the ELB, but not extract it and replace with with other - at least not through the GUI. I saw an answer from 2 years ago that suggested a rebuild was the only option - but I'm hoping there has been an update. Any suggestions?
