Thanks!

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.

I haven't used MySQL Workbench much, but using it with MariaDB should
be exactly the same as using it with MySQL.

For compatibility purposes, XtraDB identifies itself to the server as
InnoDB, so there's no need to change ENGINE= in any SQL files. 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.
