Upgrading my front page to server

I am about 80% finished with the front page but want to send my local program to the server now to detect other possible problems.

Is it any easy task to just send the finished front page to the server later or do I need to go through the entire installation from local to server?

I thought that I would get a quick response for this question since I assumed many zenners do this all the time.

I have uploaded Zen cart to my remote server.

However, I am making changes to the front page and other pages on the local computer so as not to disturb the remote server.

Now that I have made the changes to the my local computer front page and other pages how do I upload just those changes to the remote server without disturbing the product inventory and other files?

You should be able to just copy the files you have modified to the other server, particularly if you use the override system.
Don't copy all the files as things like configure.php will have information specific to that install.
If you have made the changes in a template, then it will be as simple as copying the template files over, and selecting that template.
