Thank you for the suggestion regarding the upgrade following the
Upgrading from XOOPS 2.0.* above 2.0.14 and 2.2.* (using the full package)

2 more things if I can ask:

1. In the procedure it says "2. Delete htdocs/mainfile.php, htdocs/install/, htdocs/cache/, htdocs/extras/, htdocs/template_c/, htdocs/themes/ and htdocs/uploads/ from the "htdocs" folder on your LOCAL machine" and so far it sounds logic to me but what about the "modules" folder, if I copy the 2.4 one onto the 2.3 it will erase all modules I have added after previous intallation and will find myself with System, Protector, Users and PM. Right? Do I have to replace only the ones that came with 2.4 package?

2. Regarding Xoops_Lib and Xoops_Data. I have them out of the root with 2 different names. Do I have to replace the old files with those in 2.4 full package?

Maybe I am the only one having trouble to understand it.
Thank you very much.

There is something that is not really clear to me even after having read a lot of posts.
What should I do to upgrade from 2.3 to 2.4? I do not understand. If I copy all files in htdoc from 2.4 to my server I will erase the existing ones (modules, themes, etc).
What should I do? It might be a silly question but if there is a good soul that can clearly explain that to me I will deeply appreciate it.
Thank you.
