I am migrating a server from SBS 2003 to SBS 2011 for a client, using the Migration Prep Tool. The 21 day countdown has expired, and I am at the point in the migration of moving the legacy user mailboxes to the new source server. I am remotely connected (TeamViewer) to the new server, and am receiving an error message on the destination server indicating "cannot connect to server". I'm thinking this is due to the source server being shutdown, and I need to restart it? Will I have to restart it hourly or what is the best way to continue the migration manually?
