How to go back to 1.8.1
With the trouble we've experienced in moving to 2.0, we'd like to get back to 1.8.1 in our production cluster for now while we work through our issues in a test environment. My plan was to use 'swap rebalance' to replace 2.0 instances with 1.8.1 instances. However, when I attempt to add the 1.8.1 node, I encounter this error:
Attention - This node cannot add another node ('firstname.lastname@example.org') because of cluster version compatibility mismatch. Cluster works in [2, 0] mode and node only supports [1, 8]
It appears that I need to get the cluster back into [1, 8] mode, but I haven't found any information on how to do that.
Please advise. Thanks.
