Good point. The UAT was definitely one of the reasons. It was several Excel spreadsheets long and scheduling it was a pain :-)<p>Also, it was a hosted service and  client saw no value to them- just the pain. There was risk of service outage during the upgrade that would have had resulted in the loss of revenue. Also, the client had to provision extra resources to run Cassandra&#x2F;SOA servers. In short, it was a lot of work for them with no benefit to them.
