PTAL. Note that I will send a PSA explaining that the conversion has started and
what it means for us before committing this.

Is this something we can sit together and look at on Monday, or do you want it
in sooner than that?

[rohitrao (ping after 24h), 2016-06-16 13:53:56]

The code itself LGTM, but I'd like to discuss the overall process.
