moin moin Keith,
the short answer is: move to InnoDB :)
InnoDB is much improved in 5.5, but it's fine in 5.1. If you're not
beating the heck out of the DB, then you're fine. If you are beating the
heck out of it, please bring in a DBA to help you out :).
You'll probably need to change how you're doing backups.
Does CentOS already have MariaDB? If so, move to that.
RHEL is moving to MariaDB, so CentOS is as well. I just don't know which
release first had MariaDB or in which release MariaDB becomes the default.
BTW, don't convert the internal mysql database to InnoDB, just your
application schemas.

> I have a MySql database that is about 10 years old. The tables are using the MyISAM data engine. I see the default as of version 5.5.5 is now InnoDB. The server is running a stock version of CentOS 6.4 with MySql 5.1.69. We stay with the standard CentOS upgrade and do not update Apache, MySql, or PHP to other versions.
