allowMajorVersionUpgrade

A value that indicates whether major version upgrades are allowed.

Constraints:

• You must allow major version upgrades when specifying a value for the EngineVersion parameter that is a different major version than the cluster's current version.

• Since some parameters are version specific, changing them requires executing a new ModifyDBCluster API call after the in-place MVU completes.

• MasterUserPassword

• NewDBClusterIdentifier

• VpcSecurityGroupIds

• Port
