I haven't used transactional replication in a SQL 2008 environment yet, and I'm trying to find answers to the following questions: 1) Can I use a 2008 publisher with a 2005 subscriber? 2) Can I use a 2005 publisher with a 2008 subscriber? 3) Can I use a 2008 distributor with a 2005 publisher/subscriber? 4) Can I use a 2005 distributor with a 2008 publisher/subscriber? 5) Can I run a SQL 2008 instance and a SQL 2005 instance on the same server?
