Michael here from MongoDB - We're currently still running tests on users ability to change from MongoDB to DocumentDB. It may not be quite as simple as exporting and reimporting the data. Many features present in MongoDB 3.6 do not work in DocumentDB (https://docs.aws.amazon.com/documentdb/latest/developerguide/mongo-apis.html https://docs.aws.amazon.com/documentdb/latest/developerguide...). Preliminary test results show that DocumenDB is closer to MongoDB 2.0 in its features (with some exceptions). That means people that choose to switch over will have to find workarounds and change their code to work with DocumentDB. We'll be releasing our analysis on this soon with more information.
