Hi, I would like to upgrade my OTRS version to 2.4.7 in a Windows machine. At the OTRS website (http://otrs.org/news/2009/you_tube_win/) I found a video with the instructions but when I try to launch the perl command: c:\Program Files\OTRS\OTRS\scripts>perl DBUpdate-to-2.4.pl Start migration of the system... I obtain this error message: install_driver(mysql) failed: Can't locate DBD/mysql.pm in @INC (@INC contains: C:/Program Files/OTRS/OTRS/Kernel/cpan-lib C:/Program Files/OTRS/OTRS C:/Perl/site/lib C:/Perl/lib .) at (eval 55) line 3. Perhaps the DBD::mysql perl module hasn't been fully installed, or perhaps the capitalisation of 'mysql' isn't right. Available drivers: CSV, DBM, ExampleP, File, Gofer, ODBC, Oracle, Proxy, SQLite, Sponge. at C:/Program Files/OTRS/OTRS/Kernel/System/DB.pm line 214 Doesn't the windows setup include the DBD::mysql perl module? I've tried also to follow the instructions at this link: http://faq.otrs.org/otrs/public.pl?Action=PublicFAQ http://faq.otrs.org/otrs/public.pl?Action=PublicFAQ&ItemID=351 &ItemID=351 but I have the same message.
