SQL 2008 used by Building Management Software
Have database loaded on one machine using SQL 2008 and would like to move or change to SQL 2005
Golden Rule: A SQL 2008 database cannot be downgraded or restored to a SQL 2005 version. It is not possible to downgrade a database or a database backup. The SQL schema will not allow it.
For your current version of SQL:
C:\Program Files\Microsoft SQL Server \80, \90, \100 Folders are the client tools.
80 = SQL Server 2000
90 = SQL Server 2005
100 = SQL Server 2008
How ever, it is not a rule. Since 2008 creates both 80, 90. The only way to find what versions are installed (besides regedit) is by the Sql Server Configuration manager.
