SUMMARY OVERVIEW OF NORMAL UPGRADE

site (you will need these these later in the process).
Unistall CB component.
3) Install new CB component from your CB 1.2 distribution package.
Restore your saved ue_config.php file.

Unistall your existing CB Login module and install the new one
contained in the CB 1.2 distribution package.

notes you kept earlier).

11) Done!
EDIT: ho eseguito così e tutto è andato giusto, solo in un ceck mi da giallo:
