How can I modify an auth_token of a redis cluster if the redis engine version is below 5.0.5?
As you pointed out, prior to Redis 5.0.5, changing the AUTH
token was not supported. The only way I found to do this is to stand up a replacement cluster, which at that point you should upgrade the Redis version.
