Wiki Wrote:If you don't want to overwrite everything because for instance you have customised or edited your old files or themes then the minimum you need to upload is the folder /admin/ and the file index.php .
Is there a (potential) difference between:
- overwriting the index.php and admin folder
and:
- deleting the index.php file and admin folder and after that copying the new admin folder and index.php file
?

You lose your language files (if any) in admin/lang

It typically fine to just overwrite. i overwrite.
For major releases it is usually best to do a fresh install, since there could be removals or structure changes. But hopefully in the future we will have cleanup scripts so it shouldn't matter.
