Hi, I try to upgrade OTRS 2.3.4 to OTRS 2.4.1, the database upgrade script DBUpdate-to-2.4.mysql.sql run successfully, I use backend DB as oracle 10g r2. but after when i try to run the DBUpdate-to-2.4.pl script as otrs user it gives me perl error, ................. [otrs@otrs scripts]$ ./DBUpdate-to-2.4.pl Start migration of the system... ERROR: Currently you are using Perl, but Perl v5.8.6 is required for technical reasons! In order to use this version of OTRS, you need to have Perl v5.8.6 installed. Otherwise you can also use an older version of OTRS. .............. i have no idea why it gives this because with otrs user when i check the perl version it shows correctly. as follows .............. [otrs@otrs scripts]$ perl -v This is perl, v5.8.6 built for i686-linux Copyright 1987-2004, Larry Wall Perl may be copied only under the terms of either the Artistic License or the GNU General Public License, which may be found in the Perl 5 source kit.

Thanks you Lakshan.
