There is a new JDG version, how can I update my cluster without downtime?
I need to change my cache configuration, is it possible to do this without the downtime and update the configuration node by node?
Is it possible to update an existing installation to the next minor version or do I need to install it as a new instance?
Will the upgrade from JBoss Data Grid 7.0.x to JBoss Data Grid 7.1 will be an applying a patch or a fresh installation?
When should I use Rolling Upgrade for RHDG
Is it possible to use the rolling upgrade feature to migrating from JDG6 to JDG7?
Can I use a rolling upgrade if I use embedded mode and not the JDG server?
We have several JDG clusters and all on version 7.0.1. I want to upgrade it to the latest versions.
What is a good practice to upgrade? Do i apply a patch? if yes where can i find it and how to apply? or do i have to do fresh installation? in that case what will happen to existing clusters?
