File <file name> contains service <service name> which already exists in domain <domain name>.
The <RepositoryName> or <ServerName> property in the Repository Agent or PowerCenter Server configuration file matches a Repository Service or Integration Service name in the domain. As a result, the Upgrade Wizard cannot upgrade the configuration file.
If you already upgraded the Repository Agent or PowerCenter Server configuration file, ignore the error and do not upgrade the configuration file. If you want to upgrade the configuration file again, remove the service from the domain and upgrade the file again.
