engineVersion

var engineVersion: String?

The upgraded version of the cache engine to be run on the clusters in the replication group.

Important: You can upgrade to a newer engine version (see Selecting a Cache Engine and Version), but you cannot downgrade to an earlier engine version. If you want to use an earlier engine version, you must delete the existing replication group and create it anew with the earlier engine version.
