NO, its NOT enough just to change the database connection code, you have to change the queries to the database as well. I'd stick to 5.6 for now, unless you want to undertake a complete connection/querying rewrite.

No website being created today should use mysql instead use either mysqli(improved) or PDO. Old websites which use mysql, which is NOT compatible with php versions 5.6+ the connection and querying needs to be completely revised or kept on life support until the time comes to update.
