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 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.
MySQL Enterprise Service Manager 3.4 is bundled with MySQL 5.7.20. If you are using the bundled MySQL Server for your repository (default installation), the upgrade process upgrades your repository to 5.7.20. If you are using another MySQL Server as your repository, you must upgrade it manually before installing MySQL Enterprise Service Manager 3.4. For external repositories, you must use MySQL Server 5.7.9, or higher. 5.7.20 is recommended.
If you attempt to configure a repository which does not meet the version prerequisites, the upgrader displays an error message, and the installation cannot continue.
