Add a step about removing old files to tar.gz/zip upgrade guide
Description
Currently guide tells to extract tar.gz/zip over the existing installation and then copy key files from a backup. Personally i was always doing this a bit differently. I was deleting all the old files and then extracting and copying backed up configs and database. This way no old files will be left in the installation, which can possibly create issues.
