I liked that it allowed me to use a "ghost" image of my old server, which I could then deploy to my new server. There are some limitations in functionality (eg. not allowing me to configure more than one NIC on the ghost). They were better at keeping up with patches though. It's been over 8 months since we implemented this product - and they're still actively supporting us. We did a complete migration of our servers from older versions of windows to current versions. This enabled us to do things like use newer/updated software and have more uptime.
