Our Cireson Portal implementation is in about year six now. We are using more and more 'activities' with Service Requests as we get our Request Offerings designed that automatically builds them so monitoring the status of these Activities is becoming more formal. One thing that I've noticed is we have a number (around 500) Activities that seem to be orphaned from active requests. They are accessible in our SSRS 'archive' environment but no longer accessible via the Cireson portal.
I would like to clear these Activities out somehow, so that our reports/metrics are accurate.
How can I do this? Powershell?
