I had the same issue with one of my sites, if you rewrite everything to a backup file and go ahead and implement the backup to your main folder and overwrite, delete sever cache you should have no issue at all on the other hand you can always do a full script update but you will need to tweak all your customization etc.. if you have any.I have found the backup options to work best for me I have actually implemented it on my commercial escalera lifts website and it worked like a charm for me.
