Thank you! I was reading through the comments wondering how no one has seen through the bullshit veil purported by the title, followed by a detailed outline of their migration which I think is the "shiny object" to distract people from an unfounded argument.
The main advantage of the migration was getting onto a fully managed DB. What we didn't mention was that there were also huge cost implications - savings of ~£40k - through switching to RDS - compared to paying for a mongo support contract.
