Hi, There is no option to update the configuration of an existing cache. As well, you cannot create two caches with the same name but different configurations. So, as you've correctly suggested, to achieve this, you need first to destroy a cache and then start a new one with the updated configuration. When you destroy or create a cache from a client node, there generally no need to have/propagate the configuration manually to remote nodes. On join/restart, a node will find out the caches configured in the cluster and all the required routines will take place.
Kind regards, Alex.
