Upgrade PrestaShop – Are you Ready?

by Curt Donohue on July 13, 2011


Update PrestaShopSo who wants to upgrade their PrestaShop store?  I’m guessing most of us would like to upgrade because of the perceived benefits that an upgrade can bring, but is there a downside to upgrading?  There sure can be if you don’t know what you are doing.

I want to be sure that everyone understands my position on upgrading from one version to another.  I think it is generally a good idea, especially if there are security improvements.  It may be especially necessary in that case.

However, it can be a very bad idea to update your store if you haven’t considered the consequences, which can be numerous and severe.  Two obvious consequences of upgrading can be 1) the money and 2) the time it takes to upgrade a store from one version to another.

Don’t be fooled into thinking that upgrading is just a matter following the PrestaShop PDF Upgrade Guide or their Upgrade Video.  It can be vastly more complex than either of those resources demonstrate.

In my opinion, core code changes and a custom theme are the two biggest challenges to upgrading a store.

If a store owner modified any part of the PrestaShop core code, which is very common, they would be required to make similar modifications to the new version of software.  It may not be a simple matter of copying and pasting code either since the new PrestaShop version may use a different version of PHP, Smarty, or JQuery.

One of the biggest challenges with making core code changes is remembering what you changed and where those changes are located.  Many people make changes and don’t document those changes.  I’ve certainly been guilty of that, but no more.

Now, any change I make in a pre-1.4.x version is documented in a “code-changes.txt” document that I can use to copy and paste code during the update process.  Of course, you don’t need this tool in post-1.4.x versions because of the “override” capability.

If you are making core code changes, you need to be documenting all of those changes starting immediately.  Make note of the date, file location, and the actual code that was modified.  This will save you tons of time, money, and frustration when you upgrade you store.

Because of the difficultly level of updating PrestaShop, I decided to put together a 5-part video series that will walk you through the update process step-by-step and in great detail.  Since it took me three weeks of research, testing, and video production, I can only offer this training as part of my paid PrestaShop 1.4 Tutorials product.  It’s a steal at $17/month, however.
