Whilst there are guides that specify what needs to be done often people are starting out and are not sure on the how.
Upgrading a store is just like installing an add-on.
I am assuming you know how to move files from your server to your PC using either the hosting file manager of filezilla or cuteFTP.
Step 1: Identify the add-on you want to install and download the add-on. Look at the history tab and make sure you are downloading the complete package. Some people have the annoying habit of just uploading a correction.
Step 2: Uncompress the package and read the installation instructions/readme file.
Step 3: Compress your site and copy the zip file down onto your pc, probaly best done using the hosting packages file manager..
Step 4: Unzip the file on you PC.
Step 5: Follow the installation instructions to the letter.
Step 6: For each file you have changed on your PC rename the one on the server to have _orig as part of the name e.g. file_name.php becomes file_name_orig.php.
Step 7: For each file you have changed on your PC copy them up onto your server.
Step 8: Test to ensure everything works including making a purchase.
Step 9: Breathe a huge sigh of relief and relax.
