I would start with a very careful check of any/all optional plugins and themes. Are they all *definitely* compatible and "supported" (i.e. not just used by 3 people and updated 5 years ago)?

If there is no backup, you can just download the latest 4.5 here... https://download.moodle.org/releases/supported/

There'll still be an upgrade but it's minor. If you've added plugins then they won't be there.
