We have performed quite a few SBS migrations from SBS 2003 to SBS 2011 - horrible process!
We have a client with an SBS 2008 DC, an additional 2008 R2 DC running SQL 2008R2 and a 2003 Std member server. We are going to migrate to SBS 2011 (with a new physical server). The SQL 2005 LOB on the 2003 server will be migrated to the 2008 R2 server and the 2003 server will be retired. We then need to perform the migration of SBS 2008 to SBS 2011. Should I demote the 2008 R2 server first then perform the migration? We won't want an additional DC after the migration. Is there a link to the correct procedure for the demotion? What would be the implications for LOB's on the demoted server - ALL SQL based and a couple of data shares.
