Will Upgrading Break My Site?

[ukvapeclub]

Hi guys and girls,

 

Sorry if this question has been asked a dozen times before but I can't see anything from a search.

 

We've been running PS 1.6.0.13 for quite a while now and we're encountering problems with extremely long load times (sometimes over 30s) on certain pages in the Back Office (Customers and Orders especially).

 

I'm guessing the first thing to do is to upgrade to the latest version of PS, however during the course of the last year or so we've made some tweaks to certain files (in classes, controllers) etc to customise our site.

 

(Yes, I know there are better ways to do this but we're not coding genuises.

 

Am I correct in assuming that if we were to upgrade then all our modified files would be overwritten by the default PS files, and to what extent? i.e. Will an update also affect files in the modules and themes folders, or just the main classes/controllers etc?

 

Sorry if I'm asking a bit much but a bit of guidance would be greatly appreciated

 

Thanks in advance.

Hi Stu,

 

The best approach to help you sort out impact of upgrade is to review/follow best practices, (creating copy of shop to test with):

https://www.prestashop.com/forums/topic/271082-upgrade-tips/

 

 

The key question is are you using default theme or did you install custom theme?

 

Note: when using one click upgrade, there is option,  under advanced setting if you want also default theme upgraded.  if one has custom theme they should select 'no' because PrestaShop one click will then set default theme as  current theme which makes a big mess of it.

 

Core files (but not overrides) will be updated...so any core changes should be in overrides...though they will need to be reviewed to see if compatible with the latest version.

 

So you can see building a test copy of your shop will help you understand the upgrade process and what if any impacts it will have on your production shop.

The best way to go about it is: to make a copy and upgrade the copy. Then you will know what happens.

 

To answer your question is: probably, we do not know what/how did you change so we can not say for sure.
