 2.3.4.7 Upgrading MySQL
 .......................
 
 From MySQL version 4.1.5, the new MySQL Installation Wizard can perform
 server upgrades automatically using the upgrade capabilities of MSI.
 That means you do not need to remove a previous installation manually
 before installing a new release. The installer automatically shuts down
 and removes the previous MySQL service before installing the new
 version.
 
 Automatic upgrades are only available when upgrading between
 installations that have the same major and minor version numbers. For
 example, you can upgrade automatically from MySQL 4.1.5 to MySQL 4.1.6,
 but not from MySQL 4.1 to MySQL 5.0.
 
 _If you are upgrading MySQL version 4.1.4 or earlier to version 4.1.5
 or later, you must first manually shut down and remove the older
 installation before upgrading. Be sure to back up your databases before
 performing such an upgrade, so that you can restore the databases after
 the upgrade is completed. _It is always recommended that you back up
 your data before performing any upgrades_._
