Sorry for "ressurecting" but this topic is quite "date-independent", and also the only subject relative topic I could find.

This is the old "please, look at me and help me out" kind of question, but I believe it could easyly lead into a FAQ on "How to prepare your X-Cart customizing for updates" or maybe "How X-Cart updating system works" would also be enough.


Now, taking a deeper look into my question...

I can see now that the more you customize your X-Cart, the harder updates will be.

But I wonder up to what point.

I mean, what can I customize that will not affect update and security packges? Of course, upgrades will always need a hand on re-configuring stuff because new settings will come, and old settings will be obsolete...

But, as far as I could see in 1 day, if I change only the template and database, I probably will have to do about nothing after some minor update, and specially security patches. Probably just put in there and use it.

What about changing the PHP files? Is there a limit? If I add lines to a file, instead of replacing or removing, will that affect further updates?

In fact, what I wish to know is how the update works. I only noticed it checks if it has permissions on replacing files, and I believe after that it only goes on on copying new files over the current ones. Is that all the update system does?

By the way, I am familiar with scripting and PHP, although I don't know much deeper inside on the new technologies such as Smarty and PHP Accelerator, I have no problems on customizing anything on X-Cart. I just want to know where I'm stepping on before going crazy, if you know what I mean.
