RecoverPoint for VMs - Change vCenter credentials/name

I just installed RecoverPoint for VMs using the Deployment Manager, which prompts for the IP of the vCenter Server.  In order to get it up and running quick (this is just a demo), I just plugged in my vCenter credentials.  Now I'd like to go back and change them out with a proper service account.

There appears to be no way to accomplish this via the GUI, which is ok, but the command-line doesn't work either (names/IP's have been changed to protect the innocent):

rpcluster> get_vcenter_server_credentials

Enter the IP address of the vCenter Server whose credentials you want to display (Default: All vCenter Servers at cluster):

vCenter Servers:

  10.0.0.47:

    IP address: 10.0.0.47

    User name: admin@ad.test.net

    Port: 443

    Certificate: YES

rpcluster> update_vcenter_server_registration

Enter vCenter Server name:

10.0.0.47

Error: Invalid entry: 10.0.0.47

Enter vCenter Server name:

10.0.0.47

Error: Invalid entry: 10.0..0.47

Type 'help update_vcenter_server_registration' for help with this command.

rpcluster> help update_vcenter_server_registration

DESCRIPTION:  Updates the registration details for the specified vCenter Server at the specified RPA cluster.

PARAMETER(S):

  cluster=

  name=

  [new_name=<...>]

  [new_ip=<...>]

  [new_port= ]

  [new_user_name=<...>]

  [password=<...>]

  [new_certificate=<...>]

rpcluster> update_vcenter_server_registration cluster=rpcluster name=10.0.0.47

Error: Invalid 'name' parameter.

Type 'help update_vcenter_server_registration' for help with this command.

I have tried all sorts of variations of quoting around the name= parameter, but no matter what, it will not take it.Due to this, the unregister command does not work either.

How can I change the vCenter name and credentials? 

My only other thought would be to manually remove the solution, and reinstall it using the boxmgmt interface and not using Deployment Manager.

Thanks in advance!
