You should review all your views that use ALLTRIM() to make sure that ALLTRIM() s necessary there. In WHERE clause ALLTRIM() in most cases can be replaced with '==' operator. You can post View SQL where you think ALLTRIM() is neccessary.
Even if view has been upsized, it doesn't mean it'll work correctly in SQL Server unless you're using SET ANSI ON. See http://www.berezniker.com/display/VFP/String+comparison+in+VFP for more info.
