The functionality you’re looking for is generally called Rolling Upgrade. Ignite doesn’t support clusters with mixed versions out of the box. There are third-party solutions on top of Ignite, such as GridGain, that do have that.

The problem I am trying to figure out is how do i handle version and application upgrades i.e when I am deploying the nodes in a sequence, I will reach a point where half of my nodes are in the old version and half in the newer which could lead unpredictable application behavior. Are there any ways/tricks that people have already figured out in this area that I should be aware. One solution I am thinking is to create cluster groups and deploy them by one group at a time. Please share your thoughts?? Thanx and Regards, KR Kumar -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
