Whatever the way you used to install the previous version of Shinken, you should use the same to update. Otherwise juste start from scratch a new Shinken install.
As mentioned in the installation page, 1.X and 2.0 have big differences.
Don’t forget to backup your shinken configuration before updating!
Update can be done by following (more or less) those steps :
- Create the new paths for Shinken (if you don’t want new paths then you will have to edit Shinken configuration)
mkdir /etc/shinken /var/lib/shinken/ /var/run/shinken /var/log/shinken chown shinken:shinken /etc/shinken /var/lib/shinken/ /var/run/shinken /var/log/shinken
cp -pr /usr/local/shinken/etc/<your_config_dir> /etc/shinken/
cp -pr /usr/local/shinken/shinken/modules /var/lib/shinken/
Modules directories have changed a lot in Shinken 2.0. If you copy paste the previous one it will work BUT you may have trouble if you use Shinken CLI.
