during my days with the Microsoft Content Management Server (MCMS) team, I worked with a Microsoft partner called Metalogix Software. at the time, they were the best option for customers who wanted to migrate any sort of website to MCMS.
since then, MCMS has been discontinued as a separate product, but some of the functionality of MCMS has been added to Microsoft Office SharePoint Server (MOSS). with this change, Metalogix adjusted their focus. today, their primary business is sophisticated SharePoint migration solutions.
my latest gig is going to be some contract work for Metalogix. I'll be helping them build up their product documentation and FAQ resources.
