Solution Verified - Updated -


  • 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?
