Upgrading to This Release

Amazon Neptune 1.0.4.1.R1.1 is now generally available.

If a DB cluster is running an engine version from which there is an upgrade path to this release, it is eligible to be upgraded now. You can upgrade any eligible cluster using the DB cluster operations on the console or by using the SDK. The following CLI command will upgrade an eligible cluster immediately:

For Linux, OS X, or Unix:

aws neptune modify-db-cluster \
    --db-cluster-identifier (your-neptune-cluster) \
    --engine-version 1.0.4.1 \
    --apply-immediately

For Windows:

aws neptune modify-db-cluster ^
    --db-cluster-identifier (your-neptune-cluster) ^
    --engine-version 1.0.4.1 ^
    --apply-immediately

Updates are applied to all instances in a DB cluster simultaneously. An update requires a database restart on those instances, so you will experience downtime ranging from 20–30 seconds to several minutes, after which you can resume using the DB cluster.

For more information about upgrading your engine version, see Neptune engine updates. If you have any questions or concerns, the Amazon Support team is available on the community forums and through Amazon Premium Support.
