Hello First, I have searched a lot on how to make this but no success. We want to migrate our lovely OTRS 3.0 from a windows server to a new CentOS 6 linux server. I have installed the same version of OTRS (3.0) on the linux side as well as the same version of iTSM. Both servers has the same version of OTRS's software. I have made a dump of the database on the windows side to a sql file. But, not sure if I have to: - Drop database on the linux side and import the sql file from the windows server. - Overwrite this files in the linux server. * Kernel/Config.pm * Kernel/Config/GenericAgent.pm * Kernel/Config/Files/ZZZAuto.pm * var/* - Export Setting on ADMIN/SysConfig TAB on the windows and imported on the ADMIN/SysConfig TAB on the linux side. Is it enough to make the migration? Thanks much! Regards Israel.
