If you need only to upgrade to the latest version of Miva simply copy the latest miva executable onto your Virtual Server by doing the following at your telnet prompt:

% rm ~/www/cgi-bin/miva
% cp /usr/local/contrib/miva.upgrade ~/www/cgi-bin/miva
% chmod 555 ~/www/cgi-bin/miva

Your current installation configuration and settings will remain intact. Only the binary executable will be upgraded. If you want to do a complete re-install, run the Miva install script via a telnet session with your Virtual Server. This will replace any existing copies of the miva executable and miva.conf configuration file on your Virtual Server.
