Description
In some cases users would like to do a slow roll out of the 2.X SDK, during that time they will still be using the 1.X SDK as well as the 2.X SDK. As we know the 1.X SDK cannot read documents written by the 2.X SDK. There is a work around by using custom transcoders, we should document this. We should also document any other caveats when migrating from the 1.x to 2.x SDKs.
This is stopping adoption of the 2.X SDK.
