Hi.
I upgraded my site from J!2.5 to J! 3.3.6 and I did some comparisons with a new copy of Joomla! 3.3.6 to check the differences.

It seems, the process of upgrading misses some things and some files and folders still exist.
I am posting a list of files and folders that still exists.

**Folders**
_/administrator/components/com_config/views_
_/administrator/components/com_config/models/fields_
_/administrator/components/com_config/models/forms_

**The files in that folder**
_/administrator/help/en-GB_

**Files**
_/libraries/joomla/environment/request.php_
_/media/editors/tinymce/templates/template_list.js_

**The plugin Geshi ( plg_content_geshi ) still exists.**
_/plugins/content/geshi_

**SQL**
There is a difference in the definition of the column "**_content_history_options_**" in table "**_#__content_types_**".

After upgrade from J! 2.5 to J!3.3.6 it is **DEFAULT ""**.
After a new installation of J!3.3.6 it is **DEFAULT NULL**.

Regards,
T

This handels only the files and folders. I don't know how the sql updates work that need to be added here. Also i don't know what is the correct NULL or "" Thanks.

As there can be some issues deleting folders, the files contained in these folders have also to be listed as files to delete by themselves.
Concerning geshi, if I remember well, we did decide to let it alone, although we do not provide the plugin anymore in new installs.
