7.4 Downgrade Platform Container

To downgrade the Platform Container:

1. Shut down the Platform prior to the downgrade:

   $ mzsh shutdown platform

   Note!

   If you are using SAP HANA as the Platform database, you will need to disable the TLS/SSL on the SAP HANA database before you downgrade your Platform. Refer to Downgrade 8.2 on the Release Documentation for the steps.

2. Downgrade the Platform Container by using the setup script setup.sh, that was extracted when unzipping the upgrade software.

   $./setup.sh downgrade

   
   The setup script will automatically try to detect which version you want to downgrade from ,and which version you want to downgrade to.
   
   If the script does not succeed in detecting the versions, you will be prompted for the versions.
    

3. When the versions have been determined, you will be asked if you want to proceed. Enter yes to proceed.
   
   You will now be prompted for user name and password.
    

4. Enter user name and password, and the downgrade will start.

   Hint!

   You can also add the user name and password properties to the setup.sh script.

   $ ./setup.sh downgrade -Dmz.username=mzadmin -Dmz.password=<password>

   When using the setup.sh downgrade command, three different log files will be created; generate<timestamp>.log, validate<timestamp>.log, and down- grade<timestamp>.log. By default, these log files will be placed in the same directory as setup.sh. If you want the log file to be placed in another directory, you can add the upgradelogdir property to the setup script.

   Example - Downgrading the Platform

   $ ./setup.sh downgrade -Dmz.upgradelogdir=<directory path>

   Hint!

   It may be a good idea to open a new command line window in order to keep track of the log files.

   A successful downgrade command will print out "Version successfully changed from <new version> to <previous version>" at the end of the command output.

   In case the downgrade was unsuccessful, this will be indicated. Check the latest upgrade_<timestamp>.log file for further details in order to analyze the result and see what may have caused the problem.
    

5. If any of your configurations have been resaved in the upgraded system, the configurations from the old version that was exported in section 7.2 Preparations need to be imported.
