We have a production installation of SLX 7.2 and a test installation of SLX 7.5.1. The databases for both versions are running on the same SQL Server 2005 instance. I have noticed that the SQL Server compatibility level (as shown by sp_dbcmptlevel) for both databases is 80, which appears to be identified as SQL Server 2000 compatibility. I want to run a query directly against the databases that requires compatibility level 90, which is identified as SQL Server 2005 compatibility. Will I get into trouble with SLX operation, if I change the compatibility levels of either or both of our databases?
