Server Migration Tool Feedback

I am currently running EV 9.0.1.1073 on a single Windows 2003 32-bit server.  I am planning to upgrade to EV 10.0.4 on 2008 R2. and I am looking for feedback on using the EV Server Migration tool.  What did you migrate from and to and how did it go.  Is the documentation complete or are there some got ya’s that are not accounted for in the documentation. 

Thanks you
