#Updating from mongo ruby drive 1.x to 2.x

We've recently been belatedly migrating to the 2.x series of the mongo ruby driver. At least in part this is because there's very little documentation out there on what has changed, except that there is no backwards compatibility. This post is a list of issues that we came across - I expect it is by no means exhaustive

Dependencies

Before you get started, make sure that any dependencies you have are also comaptible with mongo 2.x. For example database_cleaner needs to be 1.5 or higher
