You cannot use the update installers to change to a different operating system or chip architecture. For example, you cannot update a 32-bit Linux installation to a 64-bit version using an update installer. You must perform a fresh installation instead.
setenv.sh are lost, as this
file is replaced and optimized for MySQL Enterprise Monitor 3.0 during an upgrade.
The installation and configuration of MySQL Enterprise Monitor Agent must be standard before you start the installation. The update installer cannot upgrade agents where you have changed or modified the file names or directory layout of the installed agent.
The upgrade installer overwrites
items-mysql-monitor.xml. On Windows, this
file is in the
directory and on Unix, in the
directory. Back this file up if you have made any changes to it.
The Upgrade installer for MySQL Enterprise Service Manager overwrites any changes
made to the
my.cnf in your MySQL Enterprise Service Manager
installation. Backup the existing
file before starting the upgrade installer.
