Zencart Version Upgradation Process

Upgrade for default Zen Cart installations

Upgrading ZenCart site can be simple and complicated, depending on your existing installation zencart package, if you have just the default  setup without any modifications and third-party add-ons, then upgrade is going to be easy :-

But make sure to backup your website and mysql database to your local computer (for avoid any risk)

Build a new database to mysql and allow access to this new database for the mysql user that you already used for connect the existing ZenCart based site database.

Now you need to copy all data from your existing source database to this new database (i.e. newzencartdb), this process will be create an identical database newzencartdb to your existing  database then we will be using the new database for the upgrade process

Download a copy of latest compressed ZenCart program files, unzipped it and upload them to a new folder (i.e. newsite_zencart) in your hosting server

After that both configure file /includes/configure.php and /admin/includes/configure.php from your existing source files and folders to the newsite_zencart folder, and then change the mysql database name to the newzencartdb name, and change the path to your store to this new folder newsite_zencart of both the configure.php file in newsite_zencart folder, make sure that everything to ensure all are referencing this new ZenCart folder and the new MySQL database, this is extremely important so that you do not mess up the existing ZenCart Site while you perform upgrade

At begin upgrade process open up any browser and go for it for example  http://www.yourdomain.com/newsite_zencart/zc_install/ to start the installation process.

NOTE: You have to select Upgrade Database option instead of new installation, upgrade will keep your current database and new install will create a clean empty database

Uncheck all the steps then confirm the first step, when first step over, follow be second step, third, and so on, perform the upgrade steps one at a time so that you can isolate the issue and address them one at a same time.
