We've done lots of testing to make sure MariaDB works as seamlessly as possible for those moving from MySQL to MariaDB. As with any upgrade, I would definitely recommend making a backup and testing MariaDB on your end to ensure everything works with your applications and use-cases before putting it into production.

Any existing InnoDB tables will start using XtraDB automatically after the upgrade.

Yes. All of our testing indicates you can upgrade from MySQL to MariaDB and all of your schemas, tables, data, relations, comments, indexes, and so on will "just work" like they did with MySQL without you having to change anything. Of course, as with any upgrade, I would recommend testing on a non-production server before putting MariaDB into production. One last note. If you do find anything that doesn't work, please file a bug report: https://bugs.launchpad.net/maria/+filebug Thanks. -- Daniel Bartholomew Monty Program - http://askmonty.org
