We are in the process of migrating our server at work from Windows Small Business Server 2008 to Small Business Server 2011. There is a good article on the microsft site for working through this process. I’d recommend reading this if you are doing a similar migration (http://technet.microsoft.com/en-us/library/gg615506.aspx).
I’m planning on writing a few articles about the process of doing this migration. As a starting note I’m just going to give a note on starting the process. One of the first things to do is install the new version of the server in migration mode. To achieve this you need to create a set up answer file. This set up file needs to be placed on the root of any drive connected to the server. In our case we were installing the new server on a Hyper-v virtualisation server. The quickest way of achieving this is to create a small virtual hard disk and add the file to this.
The point we stumbled on was not reading the manual (aren’t all techies guilty of this from time to time!). The answer file needs to be called sbsanswerfile.xml or unattended.xml. We had not called the file this and was not being detected on the drive.
I’ll post more progress updates when we get further down the line!
