A) for upgrade from pre-0.29.15 to 0.29.15 : http://ehcp.net/?q=node/1047
B) upgrade from 0.29.15 to 0.19.15.2 : just replace classapp.php from new package.
Upgrade in short:
* Backup your config.php
* download new or stable or beta package of ehcp, extract it,
* restore your config.php
* logout & login back
* restart ehcp daemon: /etc/init.d/ehcp restart
ehcp directory structure has changed in version 0.29.15. so, if you are upgrading from pre 0.29.15 versions, you need to follow (A), this may be sometime problematic.
after this version, I think, replacing classapp.php or maybe a few files in future will be enaugh.
Do not forget to restart your ehcp daemon after upgrade:
