That's definitely a problem. It doesn't seem that it preserved the case of your database when exporting or importing. You'll want to check the backup to see if it was an issue when backing up or when importing.

One more thing. Just noticed that you said you've moved to MYSQL 5. The current 6.5.5 version does not fully support MySQL 5, only MySQL 4. We do fully support this in version 7 however.
