I'm currently working on several new projects that have a common theme -- much more complex applications being virtualized as a second phase virtualization project.
Among the most complex of them are Meditech servers we are currently virtualizing for several clients. If you are unfamiliar with Meditech, it certainly is classified as a more complex application that is relied upon heavily in the healthcare sector that clients wouldn't even joke about virtualizing just a few years ago.
Over the last few years we've worked with some clients comfortable being on the cutting edge and have P2V'd their Meditech servers, but I think this year just might be the tipping point where more complex application servers can be included in plans during the initial virtualization projects instead of being left for some unknown point in the future.
