Always take a snapshot of your RDS instance before any upgrade process. This ensures you have a restore point in case of unforeseen issues.
Step 3: Enable Automatic Minor Version Upgrades¶
Consider enabling automatic upgrading for minor versions in your RDS setting to streamline future updates.
Step 4: Schedule Downtime (If Necessary)¶
If you’re doing a significant upgrade, plan for a maintenance window to minimize the impact on users.
Step 5: Upgrade Process¶
- Use the AWS Management Console or AWS CLI to modify your DB instance, selecting the new version.
- Monitor the upgrade status to ensure it completes successfully.
