I have ASAvs running in AWS. I regular update the configuration through cloudformation and many times it requires a complete destroy to update the configuration in userdata. When this happens the registration is still tied to the previous instance and I have been manually going in removing the registration from the previous ASAv so the new ASAv can obtain the registration.
Has anyone found a better way to update this? I quickly looked at the smart account API, but don't see remove device which would have been a decent way add to the deployment pipeline to remove previous device so the new device can register.
