TFS Migration from 2005 to 2008?

The "rough but effective" way might be to do a full update and then "Remove Team Projects" which you don't need on the new server.
However, you have to accomplish most of what you want (with some limitations) using the TFS to TFS Migration utility on CodePlex. You might want to check out the discussions - some people are having problems with branches - you need to make sure your mappings are correct.
