How to update deployment/role to current API version?

Hi,

I'm trying to convert a Azure VM to use a static IP. When I run powershell script to add the IP, I get this error:

Set-AzureReservedIPAssociation : BadRequest : This operation is not allowed on deployment/role last updated with old API version , please update deploymet/role and try again.

How can I update deployment/role to current API version?
