I have no actual information about this migration but I wouldn’t be surprised to learn that the databases that are being consolidated are for some minor role or are separate instances with duplicate data for analytics or whatever. It sounds wildly unlikely that they are going to smush together all their customer accounts in one MongoDB instance. As well as being a huge technic challenge I’m sure regulators would have something to say about this.
