eDiscovery Platform 10.3 Upgrader fails when trying to backup MySQLData folder.

Problem

This issue will occur when upgrading a Distributed Architecture (DA) eDP environment.  If an error occurs related to the MySQLDataBackup, the installer will fail and do a small rollback procedure, making the system more unstable.  The error message says something similar to "Failed to back up  to MySQLDataBackup_1-23-2025-12.03.34".  If the installer is run a second time while in an unstable environment, a different error is seen closer to the beginning of the installation.  This error says "Build failed: D:\CW\V102\b.bat check-primary-node".

Error Message

Logs from the first failure in regards to MySQLBackup, the logs below appear in log D:\CW\Installer\log\<mm-dd-yyyy-hh.mm.ss>\cwinstall_mm-dd-yyyy-hh.mm.ss.log:

The above error tells you to then look at the log file called D:\CW\Installer\log\1-23-2025-12.16.47\cwinstall_b_check-primary-node_1-23-2025-12.17.03.log.  Here is what is in that log file:

The same log file may also show the following:

Cause

The issue in relation to MySQLDataBackup failing is still under investigation.  The second problem occurs because the installer has already installed the newer java and removed the older java binaries and because the upgrade did not complete the older version of eDiscovery Platform (eDP) is pointing to an older version of java that no longer exists.

Solution

Workaround for the MySQLDataBackup failure:
1.  Uninstall the local MySQL that is not being used and should be disabled.
2.  Remove the D:\MySQL folder
3.  Remove the D:\MySQLData folder
4.  Remove the D:\mysqltemp folder if it exists
5.  Restart the server.

Solution 1 for the second issue related to java:
Reinstall the older C:\jdk-8u412-windows-x32\jdk1.8.0_412 java back onto the server

Solution 2 for the second issue related to java:
See steps 6 and 7 from https://isearch.veritas.com/internal-search/en_US/article.100038911.html specifically for updating the config.pl file to point to the newer java installed.

Once the Workaround and one of the solutions above have been done, try the upgrade again.  If a custom upgrade, keep MySQL checked so the installer will reinstall it.
