我想改变现状 auth_token 一个redis集群。但当我更改它时，terrafrom计划告诉我它想重新创建集群：

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
-/+ destroy and then create replacement

Terraform will perform the following actions:

      # module.live_presentation_elasticache.aws_elasticache_replication_group.main[0] must be replaced
    -/+ resource "aws_elasticache_replication_group" "main" {

            ]

            }
            transit_encryption_enabled     = true

            cluster_mode {
                num_node_groups         = 3
                replicas_per_node_group = 0
            }
        }

    Plan: 1 to add, 0 to change, 1 to destroy.

我想避免重新创建redis集群。其中一些明显的原因是：我希望避免丢失数据和停机。
有没有一种破坏性较小的方法来更新auth\u令牌？优选地形溶液，但不是必需的。
