Manually upgrading the PostgreSQL version of your Amazon RDS database from 9.4 (and below) to 9.6
Platform Notice: AWS only - This article only applies to Atlassian products on the Server and Data Center platforms attached to an Amazon RDS database.
Confluence Data Center deployments created through our AWS Quick Starts are not affected.
Purpose
Starting , Amazon will start upgrading all Amazon RDS instances using PostgreSQL version 9.4 to 11. You can read about it on their announcement here.
PostgreSQL 11 is not supported on any version of Confluence. This means that if your deployment's database is an Amazon RDS instance using PostgreSQL version 9.4, you will end up with an unsupported database after .
Solution
Checking your database instance's PostgreSQL version
Remember, your database instance will only be upgraded to PostgreSQL 11 if it's using PostgreSQL 9.4 and below. Otherwise, your database should be safe from the upgrade.
- Sign in to the AWS Management Console, use the region selector in the navigation bar to choose the AWS Region for your deployment, and open the AWS RDS console at https://console.aws.amazon.com/rds.
- In the navigation pane, click Databases. From there, select your database instance. You can use the search bar to filter instances by name.
- On your database instance's Summary screen, click the Configuration tab. You can view the Engine version from there.
If your Engine version is 9.5.x and up, your instance is safe.
Take a database snapshot
Before you upgrade your database instance's PostgreSQL engine version, we recommend that you take a snapshot of your database.
- Sign in to the AWS Management Console, use the region selector in the navigation bar to choose the AWS Region for your deployment, and open the AWS RDS console at https://console.aws.amazon.com/rds.
- In the navigation pane, click Databases. From there, select your database instance. You can use the search bar to filter instances by name.
- From the Actions drop-down, select Take snapshot.
- The Take DB Snapshot page appears. Enter a name for your snapshot and click Take Snapshot.
