Hostx is working with interacting of Db so all your customization is saved in the database like blocks etc and css file that you have changed is on your staging server
Please follow these steps
Step 1. copy all files.
Step 2. export all the hostx tables from the staging server to the production server.
Step 3. all table is started from prefix mod_hostx
All your changes now shifted to a production sever except product group assigned to page as on production there might be id is different so you can reassign them again.
