Method: Aws::ElastiCache::Types::CreateReplicationGroupMessage#engine_version

Defined in:
lib/aws-sdk-elasticache/types.rb

#engine_version ⇒ String

The version number of the cache engine to be used for the clusters in this replication group. To view the supported cache engine versions, use the DescribeCacheEngineVersions operation.

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