If you’ve been looking forward to use the latest MongoDB release on NodeChef, we have some good news for you. We’ve turned on the ability to upgrade to MongoDB 3.4!
Before beginning your upgrade, see the Compatibility Changes in MongoDB 3.4 document to ensure that your applications and deployments are compatible with MongoDB 3.4. Resolve the incompatibilities in your deployment before starting the upgrade.
Upgrade process
To upgrade just log into your account. Locate your database in the dashboard. Click on DB Actions → Ops manager → Upgrade database server.
Note that once you have upgraded to 3.4, you cannot downgrade to a 3.2 or earlier version. It is therefore important to test your application in a staging/testing environment before upgrading your production environment.
As always let us know if you face any issues upgrading. Our team is always happy to help.
