We are preparing our current SharePoint Services 3.0 servers to be upgraded to SharePoint 2010. In the process, we will retire and migrate some of the old servers. This means that some of the URL’s that users are using for these old SharePoint sites will change to the new ones. New SharePoint servers would have different names from the old ones. We have about 120 users, but hundreds of short cuts, links on web pages, favorites, and the like that will no longer work. Can somebody offer some advice on how to handle this and avoid frustrate users with broken links?
