An upgrade of the Symantec Endpoint Protection Manager (SEPM) from version 12.1.1101.401 to 12.1.2015.2015 fails.
The first phase (copy and installation of files) of the upgrade finishes successfully.
During the second phase the upgrade of the database schema does not start and the following error appears:
Error : Could not create the Java Virtual Machine.
Error : A Fatal exception has occurred. Program will exit.
The Java heap memory settings are not properly configured in the upgrade.bat file.
To solve the problem locate and edit the upgrade.bat file to adjust the Java Heap memory configuration.
