Hi all! Firstly congratulations for OTRS' new version: 2.4.1! I just downloaded its windows source and tried to upgrade my OTRS 2.3.x to OTRS 2.4.1. I followed instructions in UPGRADING file but have had 2 problems: 1. I executed DBUpdate-to-2.4.pl and it showed me "Migration of the system completed!" message at final, but there were several errors regarding "NotificationEvent" with message "Need Type". It is one خب those errors: ERROR: OTRS-DBUpdate-to-2.4-10 Perl: 5.10.0 OS: MSWin32 Time: Wed Jul 22 11:00:2 4 2009 Message: Need Type! Traceback (2728): Module: Kernel::System::NotificationEvent::NotificationAdd (v1.2) Line: 228 Module: main::MigrateCustomerNotification (v1.6) Line: 218 Module: E:\Users\mohebbi\dpi\working\otrs\scripts\DBUpdate-to-2.4.pl(v1.6) L ine: 99 2. Exucting DBUpdate-to-2.4-post.mssql.sql was impossible with error message "The variable name '@defname' has already been declared. Variable names must be unique within a query batch or stored procedure." in line 31. There are 5 more errors like this. ٌI have installed OTRS in a Windows machine and did not know what services to stop before upgrading. So I didn't do anything special before upgrading except exiting any web browser that was using my OTRS instance. Now I'm using OTRS 2.4.1 with no problem even with mentioned above errors. Should I worry about those errors? Afshar Mohebbi
