Failed to update traffic switching percentage during Cloudhub 1.0 to Cloudhub 2.0 Migration

1. Verify if the user has the 'Cloudhub Network Administrator' permission. If not, request this permission from your Organization Administrator. 
2. Verify that both Cloudhub 1.0 and Cloudhub 2.0 applications are deployed and running
3. Verify that your Cloudhub 2.0 application's HTTP Listener is listening to port 8081
4. Verify that Last-Mile Security is ONLY enabled if your app has a TLS context
5. IF migrating from Cloudhub 1.0 with DLB, check to make sure that your DLB's cert was properly migrated over. 
Go to Runtime Manager - Private Spaces - <name of your migrated PS> - Domains & TLS - verify DLB's certificate was migrated. If this was not migrated please upload it here and Create TLS Context. 
NOTE: DLB requires a full chain that includes intermediate and root certs. For Private Space split the intermediate and root certs into a single file and upload into "CA Path Certificate".
