If you are able to set DHIS2_HOME as part of the tomcat startup scripts you
don't need to define any environment variables, and then you don't need to
modify the .war files either.

Not sure how this is done on Windows if you also want the tomcat instances
to start automatically on Windows startup.

Agree, using multiple live instances (with postgres) is probably the easiest
setup. Again you would like to be able to start these automatically on
reboot, but that should be possible.
