[opencms-dev] How To Setup a Cluster

[Andras Balogh]

Hello Tristan,

    This is valid for OpenCms5 or OpenCms6?
What about properties and property definitions?  Have you tried changing 
a property(ex. Title) or adding a new property definition?
These changes get reflected to the other clusters?

Best regards,
Andras.
