Is it possible to change our Redis Server to a permanent Server without losing data?

Unfortunately at this time, there is no way to do this. The act of making Persistent Redis requires the Container to be shut down and reconfigured to make use of a disk for its Persistent Storage. During this process the data is cleared. However, once the Redis Instance is set to persist this will no longer happen when Redis is shutdown/moved as it will dump its data to disk before shutting down and intermittently during runtime.
