We're starting a project to upgrade all our instances to the latest stable version (2.2.2). I've been told that the upgrade process is as simple as replacing the mongod binary and restarting the server but we wanted to verify with you first that this would have no adverse effects on the data/indexes/etc. All our boxes are at least 2.0.X so I wouldn't imagine there would be a huge problem jumping a minor version but it doesn't hurt to check.

Thanks!
