Upgrading MySQL

As a generał rule, to upgrade from one release series to another, go to the next series rather than

skipping a series. To upgrade from a release series previous to MySQL 5.5, upgrade to each

successive release series in turn until you have reached MySQL 5.5, and then proceed with the

upgrade to MySQL 5.6. For example, if you currently are running MySQL 5.1 and wish to upgrade to

a newer series, upgrade to MySQL 5.5 first before upgrading to 5.6, and so forth. For information on

upgrading to MySQL 5.5, see the MySQL 5.5 Reference Manuał.

To upgrade to MySQL 5.6, use the items in the following checklist as a guide:

• Before any upgrade, back up your databases, including the mysql

database that contains the grant

tables. See Section 7.2, "Database Backup Methods”.
