title: MongoDB: Upgrade 2.4.10 to 2.6
body: <p>I have a mongodb standalone instance in my ubuntu. According to <a href="http://docs.mongodb.org/manual/release-notes/2.6-upgrade/#upgrade-mongodb-processes" rel="nofollow">official docs</a> I replace mongod binary then I restarted mongodb using <code>sudo service mongodb restart</code> command, and restarted mongod binary also. Then when I check version using <code>mongo --version</code>. It's still 2.4.10. But when I check mongod version it's 2.6.1. Is it okay? I installed mongodb in my local machine using <a href="http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/#install-mongodb" rel="nofollow">this guide</a>. If it correct then I will upgrade my production server.</p>
