Preparations for Simplified Upgrade

The preparation steps will not affect the running system and can be done in advance.

1. Ensure that the environment variables are set correctly:

   Variable	Description
   MZ_HOME	This environment variable specifies where the software is installed.
   JAVA_HOME	This environment variable specifies where the JDK is installed.
   PATH	This environment variable specifies the search path and must contain the following directories: $JAVA_HOME/bin:$MZ_HOME/bin

   Example - Setting Environment Variables

   export MZ_HOME=/opt/mz
   export JAVA_HOME=/opt/jdk/jdk-17.0.2
   export PATH=$JAVA_HOME/bin:$MZ_HOME/bin:$PATH

2. Make a system export of all your configurations with System Export.

   $ mzsh mzadmin/<password> systemexport <backup directory>/<filename>

   Note!

   These configurations must be imported after the upgrade.

3. For safety, make an online backup of the database(s). For information about how to perform an online backup, see Backup and Disaster Recovery Procedures.
