if disabling extensions is causing a problem then don't worry about doing it before you update.
going from 3.2.0 to 3.2.2 should be very quick and straight forward.
you download the full package, unzip it to your computer.
you upload all the files except for the config.php file to overwrite/merge with the existing ones.
you go to yourdomain.com/yourboard/install
click submit for update database only
wait for it to finish
delete the folder named install
you are done.
