I've installed the upgrade estimator tool on a PEGA 7.1.8 version to estimate the cost of upgrading .
I started the estimation process but it then stuck at 0%. Server restart didn't change anything. Found the below error in the logs.
com.pega.pegarules.pub.clipboard.InvalidParameterException: cannot be null/empty. page: DataPage. Details: Invalid value for aReference passed to com.pega.pegarules.data.internal.clipboard.ClipboardPageImpl.getString(String)

Yes, While running the Estimator it will create 2 DSS rules The name of the DSS rules will dynamically create by using your current application and application version. You can delete those 2 DSS rules.
