We have 2 database servers; one is our production database server and the other is our test database server. I do my best to make sure that the database schema is identical between the two, and in doing so I noticed that the test database server is at service pack 3 for SQL Server 2005, whereas our production database server is at SP2 for SQL Server 2005. When SP3 came out I remember there being some discussion of some changes to some data types (if memory serves), but I don't think there was much in the way of major changes which would likely negatively impact a business environment which does rather run-of-the-mill type of data actions. So, is there really anything I need to worry about, when considering the possibility of moving our production database server to SP3?
