I was running v4 with a MSSQL 2005 database and decided to upgrade to v6. The installer finished successfully, however when it took me to the Web App page, there was a warning that the database upgrade did not complete successfully. The reported error was "Cannot assign a default value to a local variable". I knew right away it was a problem with my old SQL Server version. I checked the forums and indeed, 2005 is no longer supported with version 6. I understand that, and have no problem with it. However, ya'll would have saved me the headache of restoring/reinstalling if the upgrade process simply checked if the current SQL version was supported, and not proceeding with the upgrade if I am running on an unsupported version.

Thanks,
