This can be common following an upgrade especially as other poster mentioned inflated log file. You can use this script to get a breakdown of files per database and size of each file along with actual space used. If you see a lot of empty space in log files, you can shrink them to bring them back down in size (SQL will automatically grow them to the size it needs). You may also want to check whether databases are in full recovery model without actually performing log backups. If this is the situation then you'll see large transaction log files with all space used.
