Minor upgrade of Percona Server for MongoDB

If you are using data-at-rest-encryption, check the upgrade considerations for the KMIP server and for the Vault server

To upgrade Percona Server for MongoDB to the latest version, follow these steps:

  1. Stop the mongod service:

    $ sudo systemctl stop mongod
    
  2. Install the latest version packages. Use the command relevant to your operating system.

  3. Start the mongod service:

    $ sudo systemctl start mongod
    

To upgrade a replica set or a sharded cluster, use the rolling restart method. It allows you to perform the upgrade with minimum downtime. You upgrade the nodes one by one, while the whole cluster / replica set remains operational.
