Export data from test instance to rpoduction instance

Export data from test instance to rpoduction instance

I have a test instance of the servicedeskplus tool set up to test modifications.
 
We are adding support for a lot of new tools and services and have set up all the fileds in the test instance.
I need to know how to export the changes from the test instance and import them to the production instance.
 
The fields we have changed or added  are:
Category
Subcategory
Level
Priority
Request Closure Code 
Incident Additonal FIelds
Business Rules
Service Level Agrrement
Requester Additonal fields
Technician Additonal fields
Technican Groups
 
Any help would be appreciated.
