[Koha] migrating koha

hiii all, I have multiple koha instance running on one system opensuse 11. I want to shift one of the koha to another system ubuntu 12.04 as it is with out any changes. I have copied source code and paste it on another server ubuntu 12.04 i then created new koha instance and import the dump file into new koha instance, every thing goes fine but some of the searching feature are changed. On previous system opensuse when i search for records its showing me in unicode local laguage, but on the new instance records are in english language. how can i migrate the koha with out any changes like this.
