Upgrading a BYOM DB instance for RDS for SQL Server
You can apply minor engine version upgrades to your BYOM DB instances on RDS for SQL Server. Minor version upgrades include Microsoft cumulative updates that contain security patches, bug fixes, and performance improvements.
Unlike License Included instances, upgrading a BYOM instance requires a BYOM engine version to be available before you initiate the upgrade.
Identifying valid upgrade targets
Before you upgrade, identify which engine versions are available as valid upgrade targets for your current version.
Use the describe-db-engine-versions command to list valid minor version upgrade targets:
Example:
aws rds describe-db-engine-versions \ --engine sqlserver-ee \ --engine-version 15.00.4440.1.v1 \ --include-all \ --query "DBEngineVersions[?DBEngineMediaType=='Customer Provided'].ValidUpgradeTarget[] | [?IsMajorVersionUpgrade==\`false\`]"
Sample output:
[ { "Engine": "sqlserver-ee", "EngineVersion": "15.00.4455.2.v1", "AutoUpgrade": false, "IsMajorVersionUpgrade": false }, ..... { "Engine": "sqlserver-ee", "EngineVersion": "15.00.4465.1.v1", "AutoUpgrade": false, "IsMajorVersionUpgrade": false } ]
Applying a BYOM version upgrade (Amazon CLI)
Before you initiate a version upgrade, take a manual snapshot. Amazon RDS creates automated snapshots, but a manual snapshot gives you a known restore point.
Example:
aws rds modify-db-instance \ --db-instance-identifier my-byom-instance \ --engine-version 15.00.4465.1.v1 \ --no-apply-immediately
Note
When you use --no-apply-immediately, Amazon RDS applies the change during the next maintenance window. Use --apply-immediately to apply the change immediately. For more information, see Using the schedule modifications setting
Verifying the upgrade
After the upgrade completes, verify the new engine version on your DB instance.
Example:
aws rds describe-db-instances \ --db-instance-identifier my-byom-instance \ --query "DBInstances[*].[DBInstanceIdentifier,EngineVersion,DBInstanceStatus,LicenseModel]"
[ [ "my-byom-instance", "15.00.4465.1.v1", "available", "bring-your-own-media" ] ]
Confirm the following values:
EngineVersionmatches your target version.DBInstanceStatusisavailable.LicenseModelisbring-your-own-media.
Converting a License Included instance to Bring Your Own Media
You can convert an existing RDS for SQL Server instance from the License Included model to BYOM. This lets you use your own SQL Server licenses instead of paying the Amazon-included license fee.
Note
You must have a BYOM engine version in available status for the instance's current engine version.
Use the modify-db-instance command to change the license model:
aws rds modify-db-instance \ --db-instance-identifier DB_INSTANCE_IDENTIFIER \ --license-model bring-your-own-media \ --no-apply-immediately
Note
When you use --no-apply-immediately, Amazon RDS applies the change during the next maintenance window. Use --apply-immediately to apply the change immediately. For more information, see Using the schedule modifications setting
To verify the current license model of your DB instance, use the describe-db-instances command and check the LicenseModel field in the response. If a modification is in progress, check the PendingModifiedValues field for the pending license model. After the modification completes, the LicenseModel field reflects the new value. For more information, see Describing a DB instance
Considerations
Converting from BYOM to License Included is not supported.
If your License-Included (LI) instance has read replicas, remove them before converting license model to BYOM, then recreate them after. The new replicas will automatically inherit the BYOM licensing model.
If your LI DB instance is running on an instance class that is not supported for BYOM (for example, db.m5 or db.r6i), you cannot convert directly to BYOM. First, modify your instance to a supported instance class (7th generation or newer), then convert the license model as a separate modify operation.
