There isn't an official upgrade path to go from VMware vCenter 5.1 on Windows to the vCenter Server Appliance 5.5. This is how I did it.

Story
Tagline
Hardcore IT generalist, virtualization expert, blogger, photographer, homebrewer, and outdoorsman.
Introduction
Hello. I'm a hardcore IT generalist, virtualization expert, blogger, photographer, homebrewer, and outdoorsman. I ride in a Mardi Gras krewe in New Orleans, shoot sporting clays in the summer, and read a lot in the winter.

People ask me where I'm from. Ostensibly, I'm from Madison, Wisconsin, having spent most of my life living in the upper Midwest. While I've never claimed to be, I've spent enough time in both New Orleans and San Francisco to be accused, on occasion, of being a local. I take it as a compliment. I am never a tourist. I am a visitor, participant, observer, and aficionado.

Feel free to check out my writing up at http://lonesysadmin.net/ and http://bob.plankers.com/. Many more of my photos are up at http://photos.plankers.com/.
