Hello,

I'am wondering if, under HA environnement, ie with clustered EHCache and clustered DB engine, we are able to upgrade alfresco with transparency.
For example, suppose I have 2 nodes running, viewing each other through clustering (not necessarily through Load balancing).
Then I must stop the running node and deploy the upgrade version and the same for the second node.
It is not possible to have 2 nodes with a different webapp.
So in what it consist the concept of "High Availibily" ?
Alfresco Upgrades still require to shutdown all nodes and restart them one by one.
