Our support team is at your disposition for all technical problems related to the upgrade of your PrestaShop store:
Before you do anything to your current install of PrestaShop, check that your server configuration matches or exceeds the minimum requirements for the latest version of PrestaShop. For instance, make sure your web host provides you with the required versions of PHP and MySQL. If not, ask him to update the server. If you are unsure which PHP and MySQL versions you are using, ask your web host.
If you web host won't update your server configuration, then it is time for you to find a better host. Do NOT perform an upgrade unless your server at least meets the system requirements.
The minimum requirements for the latest version of PrestaShop are available on the official PrestaShop download page.
Older versions of PrestaShop might not make it as easy to upgrade to the latest version: the code base is quite different, many files have moved around, created or deleted, and the risk is high, when skipping from a very old version to the latest one, to see errors and mistakes aplenty.
You are also limited to the manual update process.
You should therefore be even more careful; the older your version, the more you should pay attention to details: backups, custom files, edited theme, etc.
