Upgrade instructions

make install-perl-modules
As the freeside UNIX user, run freeside-upgrade username, passing the username of an internal Freeside user.
If freeside-upgrade hangs, try stopping Apache, all Freeside processes, and anything else connected to your database, especially on older PostgreSQL versions.
make install-docs
Installing SOAP::Lite and POE 1.2 or later will eliminate harmless warnings when freeside-selfservice-xmlrpcd is started by the init script. The modules are not actually required unless you wish to use the new daemon.
Restart Apache and the Freeside daemons.
