Our initial deployment was years ago when Peregrine ran the software. Then HPE bought Peregrine, so I was involved in that. I've also been involved in multiple upgrades since then. We've just finished some work this week, which went really, really smoothly. It was really good. No problems. A year ago, we upgraded Universal Discovery and it took a long time to resolve all the issues. And that was using HPE Professional Services to implement it and they couldn't get to a resolution. There was R&D in China, there was HPE locally here, there was a team in the US, and there was support in Eastern Europe; all trying to work with each other across different time zones and it just didn't work very well at all. Deployment was complex.
