Procedure for upgrading a standalone MongoDB

  • Upgrade applications to use the latest Mongo Driver and then test applications to make sure they work using the latest version of driver with old database version.

  • Shutdown Mongod: > db.shutdownServer()

  • Verify that the service actually stopped using: $ sudo service mongodb status

  • Create a backup copy of all databases $ sudo cp –vrp /media/data/mongodb /media/data/mongodb-backup

  • Update apt-get package cache: $ sudo apt-get update

  • Upgrade Mongo DB $ sudo apt-get install mongodb-10gen

  • The service should restart automatically.

  • Verify that the service actually started using: $ sudo service mongodb status

  • Sign into the mongo console and verify that you are on the version that you expect. > db.version()

  • Make sure any services that may have been querying the database have been restarted.

  • Set a reminder to delete your backup after a few days.

  • Upgrade your local copies of Mongo DB on your dev machine so you are on the same version.
