Duda Sobre actualizacion Y Backup

[Piradoxlanieve]

Hola tengo instalada la version 1.0.0 y funciona genial pero no tiene algunas opciones que si tiene la 1.0.3 la ultima vez que actualice el apache se saturaba(version 1.0.3) sin embargo con la 1.0.0 va genial para poder volver a la version si algo pasara como lo tendria que hacer..

7. Backup files
# sudo cp -v /var/www/ispcp/engine/ispcp-db-keys.pl /tmp/ispcp/var/www/ispcp/engine/
# sudo cp -v /var/www/ispcp/engine/messenger/ispcp-db-keys.pl /tmp/ispcp/var/www/ispcp/engine/messenger/
# sudo cp -v /var/www/ispcp/gui/include/ispcp-db-keys.php /tmp/ispcp/var/www/ispcp/gui/include/
# sudo cp -v /var/www/ispcp/gui/themes/user_logos/* /tmp/ispcp/var/www/ispcp/gui/themes/user_logos/
# sudo cp -v /var/www/ispcp/gui/tools/pma/config.inc.php /tmp/ispcp/var/www/ispcp/gui/tools/pma/
# sudo cp -v /var/www/ispcp/gui/tools/webmail/data/* /tmp/ispcp/var/www/ispcp/gui/tools/webmail/data/

8. Delete old files to avoid security risks:
# sudo rm -fR /var/www/ispcp/gui/{admin,client,include,orderpanel,themes,reseller}/
# sudo rm -fR /var/www/ispcp/gui/*.php

9. Copy /usr and /var directories into your system (you may make backups)
# sudo cp -Rv /tmp/ispcp/usr/* /usr/
# sudo cp -Rv /tmp/ispcp/var/* /var/

10. Backup ispcp.conf and copy the /etc directory into your system (you may make backups):
# sudo mv -v /etc/ispcp/ispcp.conf /etc/ispcp/ispcp.old.conf
# sudo cp -Rv /tmp/ispcp/etc/* /etc/

11. Now it's time to update your installation. Change into the engine directory:
# cd /var/www/ispcp/engine/setup

12. Start the engine update:
# sudo perl ispcp-update

13. Update ispCP ω step-by-step

If you get no error, all went good; if you get one, look at

14. Clean the temporary folders:
# sudo rm -fR /tmp/ispcp/
